See, it made the file approx twice the size Not strange when you make 8 bits into 16 bits. Estimating duration from bitrate, this may be inaccurate ffmpeg -f s16le -channels 2 -ar 48000 -i in.pcm. If your input is raw PCM rather than WAV/AIFF, you'll need to manually set the input parameters e.g. f s16le tmp.dat and then mplayer -demuxer rawaudio -rawaudio rate44100:channels2:samplesize2 -ao pcm tmp.dat to get 'normal' wav file, many program cant read ffmpegs wav file, they read 44 bytes of header, and others data use as sound, sometimes it caused broken byteorder, or they say that file is broken and cant read file at all. Output file #0 does not contain any streamĬ:\ffmpeg\bin>ffmpeg -i Robinson.wav g723.1 -f robinsonconverted.wav PCM This will create out0.wav, out1.wav, out2.wav.

In this tutorial, we will introduce you how to convert m4a audio file to wav using python pydub. I tried the following: ffmpeg -y -i input.flv -vn -acodec pcms16le output. However, I now need the output format to be RAW, that is, PCM signed 16-bit little endian, without the WAV header. Step 2: After that you can enter the following codec to turn PCM to WAV. I'm currently using ffmpeg to convert FLV/Speex to WAV/pcms16le, successfully. I suspect that SoX might be a better tool for this job. Step 1: Open the Terminal on your Mac, go to the directory that contains files that you like to convert PCM to WAV.If.
