SNES MSU1 - Custom PCM Audio Files possible ?

[paparansen]

hi ppl...

is there a way to convert mp3 files to pcm and swap
them with the audio files for msu1 games ?

thanks in advance

Funny enough I was messing with this the other day; you have to convert your audio to wav first, then use this tool to convert to PCM format:

that is funny ^^

so, you tried and it did work?

 

[samedifference]

Yeah, I had no problem converting to PCM from wav format with this tool. As long as you follow the instructions listed in usage.txt, it shouldn't be too much of a hassle (unless you're unfamiliar with using command prompt).

 

[paparansen]

i meant did you successfully swap the pcm files for a msu1 game?

 

[samedifference]

Yes, you just have to make sure the filename is identical to the audio track you're replacing.

ok then... 1 last thing: how can i playback pcm files on a windows 7 machine,
so that i can choose the correct pcm files to swap?

 

[samedifference]

To preview PCM files, you can open them in Audacity under Import > Raw Data, make sure the encoding is set to 'Signed 16-bit PCM' and the byte order is set to 'Little-endian'.

playback is slow with that setting... samplerate?

 

[samedifference]

If it sounds too slow, setting the sample rate to 88200 should sound right, otherwise you might have to experiment a little bit with the playback rate.

will give it a try... thank you for the hints

kudos
