Hey @zep!

Can you please add a feature to PICO-8's WAV export function, so that each of the four channels have one WAV file each? I've been wanting to do oscilloscope views of PICO-8 chiptune music, but the "oscilloscope view" format requires one WAV file for each channel (so that each channel is seen as a separate waveform).

I've already mentioned you on Twitter about this, but you never replied:

there should also be a setting in the config.txt where you can put how long you want the wav to be.

Sure! What else??

P#68959 2019-10-17 10:47

why not simply mute the channels?

That's what I want. Implementing it shouldn't be too hard.

I mean - you can do it.
There is no need to add this feature for that single use case!

@StinkerB06, how about this ?

This will play each of the first SFX tracks of demo music from @zep. It also saves them off as individual WAV files.

HOPE THIS HELPS !

@dw817 That seems to work, awesome! I'll perhaps modify your code to fit my needs.

However, the only problem is that this may not work with all songs made on the PICO-8, especially ones where different SFX SPD's are used on the same music-frame number.

Glad to help. And yeah, it may not work for everything. But enough to get you started so you can examine their wave tables in sync.
