How to convert mp3 to wav with specific options

audiomp3wav

I need to convert mp3 files to 8KHz PCM-code 64Kbps bitrate wav file. Is this possible with lame or mpg123, or any other programmes?

Thanks.

I'd recommend Audacity. It's a free audio editing program that runs on Windows/Mac/Linux.

From poking around in the formats that you can export, if you save as type Other uncompressed files and select Options, you have the ability to select a WAV file Unsigned 8 bit PCM encoding which I believe is what you were looking for.

Converting .wav (CCITT A-Law format) to .mp3 using LAME

You want to use SoX to convert the A-law input data to a more standard PCM data for LAME to process.

sox -A -c 1 -r 8000 input.8khz-mono-alaw.wav ouput.wav

Now output.wav should contain standard PCM WAV data. Run your LAME command on this (add whatever options you like):

lame output.wav output.mp3

Or, pipe the SoX output into LAME directly:

sox -A -c 1 -r 8000 input.8khz-mono-alaw.wav - | lame - output.mp3

Convert a .mp3 to wav file with mplayer

ffmpeg should do the job. This line will convert to 8kHz 1 channel wav file.

ffmpeg -i input.mp3 -ar 8000 -ac 1 output.wav

I'm not sure about the 8 bits requirement - what are you referring to? It's not the bitrate surely?
