Best Free Software to Cut or Merge Audio Files

 
In a Hurry?
  Go straight to the Quick Selection Guide: Audio Cutters / Splitters | Audio Joiners
Introduction

So, you've got some big mp3 or other audio files which you want to trim, splice, split or otherwise cut down to size, maybe for your mp3 player. Perhaps you want to extract one or more songs from a large audio file, or a particular part of a radio program you recorded (cut-out the commercials!). You want to split a wav file you've transferred from vinyl into its original track. Or you want to use a particular portion of an mp3 file to create a personalized ring tone for your smart phone.

You could use an all-round audio editing freeware program like Audacity, but that isn't the most convenient or efficient way. Your best bet is probably to use a smaller, more specific program for the job: a lightweight freeware splitter or joiner. Perhaps something you can run even on an oldish laptop. And you'll be better off choosing a lossless splitter which — unlike Audacity, for example — will cut (or merge) your files without any loss of sound quality due to decompressing and recoding.

This review will focus on simple audio cutter/joiner freeware for use with mp3 and ogg files, and also for wav and other formats.

Discussion

Audio Cutters / Splitters

mp3DirectCutmp3DirectCut is likely to be top choice if your main need is simply to cut/split mp3 files. It's a lightweight, portable, lossless mp3 splitter which is a joy to use, even on less powerful computers.

Like other top audio file splitters,  mp3DirectCut  incorporates an audio player with a volume unit (VU) meter which lets you see as well as hear the points where you want to cut. Mp3DirectCut offers a good range of handy features, including pause detection, CUE sheet support, looping, volume gain, fading, trimming and ID tagging, etc.

It's a pleasure to get to know this no frills program. There's an excellent manual (available here or here), as well as a useful tutorial on how to make a ring tone with mp3DirectCut. Splendid, straightforward portable freeware.

NB: A particular strong point of mp3DirectCut used to be the clarity of its neatly arranged interface (as illustrated above). However, the most recent version has sacrificed the logical descriptive buttons for a graphically questionable slew of symbols (screenshot here). Therefore, we continue to recommend the older version, while providing download links to both versions. Take your pick.

mp3Splt-gtkmp3splt-gtk has the advantage that it handles ogg vorbis files as well as mp3. It also has a few more features than mp3DirectCut, including the ability to identify split points between tracks via online database services (CDDB or FreeDB).

On the downside, the user interface is less tidy than mp3DirectCut's (at least in its older versions), and the program's response times tend to be somewhat longer. For instance, you have to load the player's VU meter (by checking "Show amplitude wave"). Documentation too seems to be confined to the command line version of mp3splt. However, you can find a good overview of the program and its interface here.

Audio Joiners

MakeitOne MP3 Album MakerMakeitOne MP3 Album Maker outshines other joiners for its ability to join multiple mp3 files and, if required, "unpack" them back to their original state. Either way, the program is a lightning fast mp3 joiner and unpacker that accepts large files.

The mp3 files packed by the program can be played on any mp3 player. It features drag-and-drop files for ease of use and includes a tagging function which lets you tag artist and album title information and album art to the joined files.

On the downside, the only audio format it supports is mp3.

Shuangs Audio JoinerShuangs Audio Joiner takes three simple steps to join audio files, Add files in the list, Select Output Format, and Join the files; straight forward, easy to use and effective.

Joins mp3, wma and wav files. The mp3 files can be joined using a bitrate ranging from 32 to 320 kbps, wma files with a bitrate ranging from 48 to 160 kbps.

The user interface shows a small advert panel linking to the developer's homepage but it is not intrusive.

Online applications:

  • cutmp3.net - There are several valid online mp3 cutters around, but for straightforward jobs CutMp3 really is a cut above the rest. Since cutmp3.net doesn't require you to upload the mp3 file, this app works lightning fast. There is no limit to the size of file you can use, and all in all cutmp3.net really cuts the mustard!
  • Audiko.net - If you have proprietary ringtone needs, then Audiko may provide the answer. This app lets you cut an mp3, ogg or aac audio file online easily, and could be good for creating a personalized ringtone for iPhone or other smart phones without installing any software. Just upload a file, choose the best fragment by dragging the start and end point on a volume unit (UV) meter while the audio file is automatically being played. Then, click the Create Ringtone button and download the file in mp3, m4r or an amr format directly to your mobile or smart phone; you'll have to send a text first though.

More freeware review suggestions:

  • Merge MP3 - A strong contender for best free joiner based on its ability to merge mp3s very rapidly without the need to re-encode. Recommended by Gizmo reviewer mr6n8, here
  • mpTrim - This portable program will remove silent parts of mp3 files. Its sister program - wavTrim - will do the same for wav files.
  • Ventones.com - Another web site to create ring tones online from your mp3 collection; or download free ringtones made by others (free registration required).
  • Free Audio Dub - This standalone program promises to let you cut a variety of audio formats, including aac, ac3 and m4a (as well as mp3, wav, ogg, wma and mp2). So Free Audio Dub could come in useful for iTunes files. INSTALLATION NOTE: The installer asks you to install the Ask toolbar and set Ask as your home page and default search engine: to opt out,  uncheck all three tick boxes when installing.
  • Medieval Cue Splitter - Good for other audio file types if you want to split into original CD tracks a ripped audio file with an accompanying CUE file; supports mp3, flac, ape, ogg, wma, mpc, wv (lossless WavPack compressed) and ta (True Audio codec) files.
  • Free MP3 WMA Cutter - Also includes several basic audio file editing functions and can be used as a ringtone maker for iPhone, Blackberry, Nokia, etc.
  • Free MP3 Joiner - Drag and drop (and can also convert several audio file types).
  • Meda MP3 Joiner - Another contender.
 

Tested and not recommended:

  • iWisoft Free Video Converter - This excellent freeware video converter successfully cuts mp4 video files, but it isn't primarily an audio file cutter. Since the developers used to claim the program could cut and merge a wide variety of audio file formats I decided to try to split a Monkey's Audio ape file; the results were not good (far easier to decompress to wav and then split with CD Wave Editor). Still... worth watching.
  • Slice Audio File Splitter - Partial reliance on an ambiguously "freeware"  audio editor (Wavepad Basic) is an annoyance... as is the stuff these two programs write to the registry.
  • Sofonica MP3 Cutter (sofonica[dot]com/?q=node/17) - Supposed to cut ring tones, but on Vista proved impossibly buggy. 
  • Weeny Free Audio Cutter (weenysoft[dot]com/free-audio-cutter[dot]html) promises some interesting features but has yet to reach the testing stage due to some equivocal AV scans and adware issues. 
How to cut and join .wav files

If you're transferring LP records or tapes to your computer, or otherwise making high quality audio recordings to store and play from a hard disk or music player, you'll probably want to work initially with a pristine .wav (pcm) file before converting to a compressed format. This process is valuable if you're going to store your audio files in a format which can't be split, such as high quality lossy .mpc (musepack).*

  • CD Wave Editor - will let you seamlessly cut wav files as long as your computer has enough RAM. Remarkably, CD Wave Editor will also let you split lossless flac, ape and w64 (Sony wave 64) files directly by decompressing them to wav on the fly.
  • CD Wave Editor has a built-in audio player and VU meter to help you select the points where you want to cut. The neat interface conveniently color codes the portions you've selected and lets you uncheck the boxes of any portions you don't want to save. What's more, if you don't want to save your cut files in wav format, CD Wave Editor will compress them for you to lossless flac or ape, or convert them to lossy Vorbis ogg or mp3.
  • Although CD Wave Editor is technically shareware rather than freeware (the developer requests $15 if you decide to keep the program after a month), the evaluation version doesn't actually expire and has no practical restrictions (All Windows platforms up to Vista, 1.2 MB).
  • Wave Splitter - This tiny, highly efficient and portable program provides an alternative way to cut wav files. Since it doesn't consume any RAM, WaveSplitter should be particularly useful on less powerful computers. The final version of this little freeware gem dates back to 2000, but it seems to work just fine even on recent platforms like Vista (0.3 MB).
  • WavMerge - Allows you to join .wav files. One of the few programs of its kind (along with Shuang's Audio Joiner), WavMerge is neat and simple to use; just mouse over the radio buttons to see their functions. Another oldie but goldie portable executable (dating from 1998) which runs fine on Vista. [0.8 MB] 
 
*A few words about how to cut or merge tricky audio file formats:
  • If you're working with files already compressed into a lossless format like .flac or .ape, you can just decompress them to .wav without losing any information and then use one of these tools before compressing again to whatever format you need (CD Wave Editor will do all this for you from inside the program).
  • If the file you want to work on is a lossy one that can't be split (eg musepack), you can follow the same procedure by converting to wav or mp3 etc and then cutting; however, you'll inevitably lose some information and impair the sound quality. So, in that case it's much better to edit the wav file before converting to the compressed lossy format.

Update: Merge MP3 flagged for priority review (based on Steve's recommendation below)

by mr6n8 on 7. May 2011 - 11:39  (71574)

I will point out that it is a simple app-doing only what it says, without any other major options.

I like it because it is like the old time freeware I used to find. Someone wanted to do something on the computer, could not find a program and developed their own and released it for free.

Funny that I found it here even though it was not listed under the prime listing. I can't remember how I picked it out of the bunch.

Steve

by Bob on 7. May 2011 - 12:33  (71577)

You're quite right Steve - thank you.
Btw, I see this BF category is up for grabs if you'd like it :)

by mr6n8 on 7. May 2011 - 22:24  (71590)

maybe down the road if it is still open.

I am updating all my book pages right now and will be on the road for a month or so soon.

I thought this was yours

Do we know of a reliable mp3 merger/joiner that can do the business without the need to encode as per my earlier message here.

by mr6n8 on 6. May 2011 - 20:05  (71544)

I use Merge MP3-just tested to make sure and it merged a 256 with a 192 almost instantaneously.
I have it set to use Raw Stream Mode-not sure if that makes a difference-it has been a while since I set it up. Preferences is under View.

Did you need to execute the itunes.exe?

by mr6n8 on 6. May 2011 - 22:00  (71549)

No. I think that is to convert MP3 into M4B audiobook for listening to an audiobook in iTunes. I have combined audiobooks, but only to MP3-I only listen off of laptop.

My VBR frame is set to auto and thread priority normal-I am thinking all of the settings were default-but am not sure.

The only other thing I can think of is that I always "select all" under "Select" after the songs are loaded and organized and then under "File" choose "merge selected".

BTW the combined 256 and 192 shows as a "255kb/s tot. Joint stereo" in gspot-whatever that means. Anyways quality is always good.

by Bob on 7. May 2011 - 9:32  (71570)

Thanks very much for this Steve :)
Your recommendation goes to the top of the "to be reviewed" list. I'll have Merge MP3 go head to head with Shuangs.

by Anonymous_vbsoh (not verified) on 7. May 2011 - 10:08  (71572)

let's see what e-merges :D

by Jimz (not verified) on 6. May 2011 - 19:01  (71542)

I went for the Shuangs Audio Joiner, and it works fine, however just one little thing I noticed, and that is if you are merging say 320 bitrate files to the same bitrate for example 320 to 320, the program still encodes the file data, and I would have thought that there should be an option to join as source bitrate without the need for encoding.

This of course would save time too.

My first impressions were that Weeny Free Aduio Cutter has some interesting features, including support for cutting and merging .wav, .wma and .ogg files.

EDIT: But Anupam warns
I finally managed to test this in a virtual environment. I uploaded the InstallManager to VirusTotal, and got 7/40 result. Here is the link.

http://www.virustotal.com/file-scan/report.html?id=6c93ca3718edad2cecc75...

GData, Avast, SAS are marking this file as positive, so it makes me suspicious.

Also, I completed the installation, and towards the end of the setup, a window was displayed from which I could download Real Player. This was displayed by InstallManager.

Personally, I dislike such programs, which show such behavior. The sole purpose of downloading InstallManager is to display a screen from where you can download third party software. That's adware.

Dont forget AUDICITY, very good

by Bob on 20. April 2011 - 4:49  (70577)

Audacity is indeed a very good program. But, as mentioned in the Intro to this review, Audacity does not do lossless cutting, splitting or merging: you can do all those operations, but you lose some of the original data. This review focuses on the best free *lossless* cutters (and joiners/mergers, splitters)

by Geert on 6. March 2011 - 19:14  (67535)

I agree with Bob when he says about mp3DirectCut:
>> A particular strong point is the simplicity of its neatly arranged interface

But I was somewhat disappointed when recently I installed the last version of mp3DirectCut where all the text on the buttons was replaced by a bunch of - not always that clear - icons. In my opinion that was - maybe a step forward in the category "having a sexy look", but certainly - a step back in userfriendlyness.

by Bob on 9. March 2011 - 15:46  (67694)

Thanks for flagging this, Geert. I fully agree with you. Er, scarcely cutting edge, I'd say. And I don't even find the new buttons particularly sexy on her. Anyway, an older version (2.12) of mp3DirectCut with the more descriptive interface can still be downloaded  from here 
(I've updated the review.)

by Niefer (not verified) on 19. April 2011 - 7:38  (70512)

You can just switch buttons / text:

Settings \ Configure... \ Operation \ Button layout

by Bob on 19. April 2011 - 11:07  (70519)

Yes, that's true. But I'd suggest that the text buttons would be a better default layout; personally, I didn't feel the need for the textless layout, especially when the text is so neatly integrated with the buttons.

In the current version (2.13), you additionally always get an toolbar at the top of the window with some useful mouseover buttons. However, I was surprised to find the toolbar remained even after I selected the "slim"[?] layout option.

My own preference would be to have a dropdown "View" menu to make it easy for users to set their preferred appearance without having to restart the program each time. But I realize that sort of solution might be difficult to code within such a small and efficient package (with the main program consuming just 78 KB of disk space and few CPU resources).

by Anonymous1 (not verified) on 30. January 2011 - 2:26  (65487)

I have used mp3directcut for several years. But when I switched to W7 it will not load, play, record or edit any audio. The only thing different is I have MagicJack in one USB port but I don't see how this could affect it. I played with computer settings but no luck. Any help would be appreciated. Thanks

by Bob on 1. February 2011 - 16:50  (65634)

Personally, I can't think of anything off hand other than a system issue. Try posting your query on Gizmo's Freeware Forum: http://www.techsupportalert.com/freeware-forum/freeware-installation-and... Someone may be able to help.

by Stacey (not verified) on 27. December 2010 - 13:08  (63349)

Could someone please help me........I am wanting to take some songs in my files and only use part of them. I play music at my sons hockey games and sometimes only have 10-25 seconds to play a song so I want to play the best part of the song. I am not real good w/ the computer so I need something that is very user friendly. Someone suggested acidpro but I found this hard to get around. Is there a free program that is simple to use???? I don't need to do any other crazy stuff to the songs, just cut the pieces out that I want to use (10-40 secs worth).
Truly would appreciate some help.
Stacey

by Bob on 27. December 2010 - 13:12  (63350)

Hello Stacey.

Have you tried CutMP3.net? I think you'll find this online app really simple. However, since the site doesn't actually provide any instructions, I'll briefly talk you through the job. I'm assuming that the files you want to use are mp3 (and that you don't happen to know in advance the exact timings of the points where you want to cut).

To use CutMP3.net, go to the webpage (http://cutmp3.net/), click 'Open MP3' and select the file with the song you wish to cut. Wait for the file to load (this shouldn't take too long unless the file's too big for the app). Press 'Play' and listen till you get to the point where you wish to start your personal selection and then press 'Pause'. When you're satisfied that you've paused at just the right place, you can select the start of your soundbite by dragging the left-hand bottom cursor to exactly the point you paused at (reddish orange line). Now repeat the process, this time using the right-hand bottom cursor to select the end. In other words, continue playing the track, pause where you want your song to end, and then drag the right hand cursor to the chosen point. Your selection should now be highlighted in blue. Finally, press 'Cut', rename the new file (for example, "extract.mp3"), and save it wherever you want. You should now have the soundbite you need.

Hope this helps
Bob
