This means WAV files have higher sound quality, which is why many musicians prefer to record and play music in WAV format. However, because the files aren’t compressed, the downside is that WAV files can be much bigger than other audio formats – up to 10 times the file size of an MP3.
Convert Audio Formats. 20210607. A simple way to convert between audio formats is to use ffmpeg. Whilst this is a video processing tool it also handles audio, of course, since most video includes audio. The same commands are also useful to extract just the audio track from a video. To convert a mp3 file to wav: ffmpeg -i myaudio.mp3 myaudio.wav.
If you are exporting a constant bit rate spoken word MP3 such as an audiobook and have a stereo track in Audacity where both channels are identical, it is preferable to use Tracks > Mix > Mix Stereo down to Mono to convert to a single mono track before export. This will still sound the same on stereo equipment, but have higher quality because
1. The final file must in WAV format. 2. The final file must be 16-bit mono format. 3. The sample rate must be 8 kHz. 4. The file size must be under 4 Mb (the smaller the better). To do the conversion I will use Audacity, a free, open source, cross-platform audio editor. Step 1. Load WAV file into Audacity
Auvisoft Audio Converter converts audio formats AAC, ADPCM, Dolby Digital AC-3, GSM, MP2, MP3, OGG, VOX, WAV, WMA from one to another, such as converting MP3 to WAV and WMA, WAV to MP3 and WMA. AAC means "Advanced Audio Coding", and in the beginning it was also called MPEG-2 NBC for "Non-Backwards Compatible" as opposed to the MPEG-1 and MPEG-2
The simplest way I can think of is using the PyTorch mean function as in the example below. import torch import torchaudio def stereo_to_mono_convertor (signal): # If there is more than 1 channel in your audio if signal.shape [0] > 1: # Do a mean of all channels and keep it in one channel signal = torch.mean (signal, dim=0, keepdim=True) return
“CD quality” (16-bit, 44.1kHz) is generally better than human hearing so as long as you stick to 16/44.1 or better, re-sampling shouldn’t affect sound quality. MP3 is lossy so you MIGHT hear some quality loss when you convert to MP3, especially at low bitrate/quality settings. There is additional loss if you re-compress MP3.

For instance, to convert a "raw" audio type to a ".wav" file: ffmpeg -f s32le input_filename.raw output.wav You can specify number of channels, etc. as well, ex: ffmpeg -f u16le -ar 44100 -ac 1 -i input.raw output.wav The default for muxing into WAV files is pcm_s16le. You can change it by specifying the audio codec and using the WAV file Take the file you recorded and copy it to your computer. We will need to convert the file into a 22,050 kHz, 16-bit, mono WAV file for your project. Use the guides below to get a digital sound file to use in your projects.
