Seamless sound loop?

SDK Get Help
#1

Is it possible to seamlessly loop audio? I'm getting a relatively significant gap between loops. It is a wavy tone with no gaps in it, so it's easy to hear where the loop ends/begins. Wondering if this has anything to do with me or it's just not going to be possible.

I can confirm that the audio file (.wav) doesn't have any gap in it and loops seamlessly in Audacity. And it's only about 1.5 seconds long, so it's not very large.

I am using a sampleplayer for this:

sndIntro = playdate.sound.sampleplayer.new('audio/intro')
sndIntro:play(0)

I may consider trying to recreate this sound with the synth object (or similar), but this method is so much easier and is the exact sound I need in my game.

At some point in the past, I had a similar issue. I ended up using the :setLoops() function, and then just setting it to loop at an explicit value.

Note that this function uses a Sequence (so you'll need that set up too), and that it takes "steps" as its value, and I'm not 100% sure what that value is in relation to seconds. Looking back at some old code, I had a 48s long .mid file (doesn't have to be a MIDI file though), and had it looping at the 46,100 steps point, for some reason that I can't recall. Vaguely it was something like:

menuMidi = playdate.sound.sequence.new('assets/audio/menu-music.mid')
menuMidi:setTempo(950)
menuMidi:setLoops(0,46100)

@fosterdouglas Hey, thanks a ton for the suggestion. I'll play around with this method and see if I can get this to work. I'll report back here with any success.

In Audition I use fileplayer for perfect loops, not sampleplayer.

Would you mind posting the file here (or DM it to me if you don't want to share it publicly for whatever reason) so I can see if I can reproduce that? It should be looping seamlessly but this is an area where new bugs keep popping up as I fix others, so I wouldn't be surprised if something creeped in. :confused:
