The volume smoothing of the IoTiny, which uses a different audio technique, affected the v4. The code is reverted for the v4 and a new module controls the IoTiny only.

Thanks DJ, the lastest release fixed the problem.

big thank you @ DJ Sures

Update:

the soundboard works fine but sometimes I can hear the clicking noise.. the problem is not completely fixed.

example:

my robot follows his red ball..
every time he locates the ball he says: "my red ball"..

if the sound plays in in quick succession it makes a click noise.. (If I change the ball position fast)

regards

The code is original to what was there before. This is fixed as it was. The click is most likely due to the fact that the volume between the two sounds at the sample point is dramatic different positions. You can research how audio works to understand further, as you are playing multiple sounds not a single sound.

For example, if the last sample of the previous audio was the value of 208, and the first sample of the next audio is 54... there will be a click while the DAC jumps between the two voltages.

That's just how it works. You will have to accept that click between samples if you do not let the audio completely play, assuming that the audio ends with 127 and the next audio starts at 127.

The value of 127 is 0db on 8bit audio

@ DJ Sures

oh okay, thanks for the lesson

cheers Marty

Anytime

I have been thinking of different ways to remove the click, but no success yet. One day i will come up with an idea
