0.0.18-alpha.6: Microphone sample data too large

[marvpaul]

This bug also happened in 0.0.18-alpha.4. I noticed because I'm generating a FFT spectrum from the sample data I'm fetching from the microphone using your VideoKit to generate a audio reactive component. With the updated version 0.0.18-alpha.4 / 0.0.18-alpha.6 it breaks my audio reactivity. After doing some research and comparing it with the previous version of Videokit (0.0.18-alpha.2) it seems to come from extraordinary high values inside the sample buffer. I noticed two main differences:

0.0.18-alpha.2 (audio reactivity works)

• sample buffer data always < 1
• sample buffer length around 940

0.0.18-alpha.6 (audio reactivity dosen't works)

• sample buffer data sometimes as large as 3.928899E+11
• sample buffer length > 3000

here's a repo where I reproduced the bug with no other dependencies. The script GetSamples uses the builtin microphone and commit the samples to the method CommitSamples. I just print out sample values > 1 here.

@marvpaul what platform does this happen on? I presume it's on the Unity Editor, but is it macOS or Windows?

Yes, it happens in the editor on Mac OS. Strangely enough it worked as expected in 0.0.18-alpha.2. I also tested the sample project with 0.0.18-alpha.2 and it works as usual, whereas alpha.4 and alpha.6 produce those unusual high values.

I'm pretty sure I've found the cause. Will confirm and push a new alpha build for you to repro.

Solved in your latest alpha! 🎉

Perfect!
