Strange sound at iOS

[cool2apps]

I build a gaming emulator with flutter and sound is working not so bad (but not perfect) at android but the sound is very weird at iOS. What could be the problem? Any idea?

the sound is kind of flickery?

no im not sure the cause. make sure you are feeding enough pcm samples regularly.

Hi, The same thing is happening to me.
I use cosineWave().
What code gives enough pcm samples?
It would be helpful if you could give us some sample code.

[chipweinberger]

there is an example in the repo already

Thanks. You are indeed right, cosineWave() was called within generate().
I'm writing the following code to sound a chord,
but it sounds weird only on iOS.
Does this code have sufficient pcm samples?

frames = zip([
                scale.cosineWave(
                    periods: 441, freq: 440.0, volume: 0.2), // Root [C]
                scale.cosineWave(
                    periods: 441,
                    freq: 440.0 * (5 / 4),
                    volume: 0.2), // Major Third [E]
                scale.cosineWave(
                    periods: 441,
                    freq: 440.0 * (3 / 2),
                    volume: 0.2) // Perfect Fifth [G]
              ]).map((values) => values.reduce((a, b) => a + b)).toList();
