combine multiple wav files together with different sample rates / channels / bits

I have a folder with lots of wav files, all different samples/ rates/ bits

Most of them are just a mix of mono or stereo

is there a way using sox and bash, or another built in app that can convert them all to a uniform format?

Yes, of course ;-)

This page might give you some additional tips:

But my guess is you're going to have to figure out the "right" settings on a file-by-file basis, by trial and error...

IMHO .. PSM

Hi.

Not 'built in', but if you've got a copy of mplayer...

Code:

#!/bin/bash



if ! [ -e "$1" ]

then

    echo "$1 does not exist."

    echo "Exiting."

    exit 1

fi



INFILE="$1"



if file -L "$INFILE" | grep RIFF | grep PCM | grep "16 bit" | grep stereo | grep 44100 &> /dev/null

    then

    echo "$INFILE is already a 44100Hz 16bit LE file."

    echo "Exiting."

    exit 0

fi

if [ -e "$INFILE".wav ]

    then

    echo "Decode output file: $INFILE.wav already exists."

    echo "Exiting."

    exit 1

fi



if ! mplayer -vo null -vc null -af lavcresample=44100,channels=2,format=s16le -ao pcm:file="$INFILE".wav "$INFILE"

    then

    echo "Couldn't decode $INFILE"

    echo "Exiting."

    exit 1

fi

I called it 'any2wav' - run as:
$ for file in *; do any2wav "$file"; done
and it'll convert anything (even video audio tracks) to CD style .wav

I've got slightly different versions that do the same thing, but output mp3s or FLACs, if you're interested:
