Audacity is the main program and ffmpeg is an extension that Audacity uses to open. Audacity and ffmpeg are open source programs that can convert audio into different formats. mp3 using the app Audacity and the ffmpeg plugin. To do this, you'll need to convert your audio that you recorded in the Voice Recorder from. M4A/MP4/AAC is also lossy but it does not suffer from accumulated damage like MP3 and some other formats.Ringcentral requires audio files to be saved as. You may need FFmpeg or other formats and installing it isn’t really that hard… Just download and RUN the FFmpeg Installerinstaller ( FFmpeg_v2.2.2_for_Audacity_on_Windows_64bit.exe) and it will install in the right place and you should be ready-to-go! (You may need to re-start Audacity and if you have the 32-bit version of Audacity you’ll need 32-bit FFmpeg.) There are some special-purpose editors like mp3DirectCut that can do limited editing without decompressing. You may not hear any quality loss but it’s something you should be aware of. If you export as MP3 the new MP3 has gone-through another generation of lossy compression and some “damage” does accumulate. Audacity is going to decompress when it opens it anyway.Īs you may know, MP3 is lossy compression. It can optionally use FFmpeg to open MP3s and it’s more forgiving than the built-in decoder but I forgot the trick that tells Audacity to use it… It’s just easier and more foolproof if you convert/decompress to WAV (or FLAC). If it’s MP3 it will say 'MPEG Audio (Version 1) (Layer 3)'.Īudacity doesn’t need FFmpeg for MP3s. MediaInfoOnline can tell you if it’s an MP3 but it won’t tell you if there’s a problem. Audacity is going to decompress the file anyway so although it’s an extra step for you, it’s basically the same process. The easiest solution is to convert the file to WAV or FLAC with a 3rd party application like KabuuAudio Converter or TAudioConverter. Audacity is more picky about MP3s than most other software and there are a lot of “bad ones” out there…

I assume the files play in Windows Media Player, etc?Įither it’s not really an MP3 or it’s an “imperfect MP3”.
