Question

Hi there!

I updated to the newest Software: Version 2016.05.17.00 If I playing Soundboard V4 MP3s the robot speaker makes bad clicking-noises. first I hear a click, then play the sound..

I deinstalled the software and used an 1 month older version.. now its without any click-noises..

I updated to the newest software again.. the bad click-noises are back! stress

is this a new future or a bug ?

That's strange - can you share an example project that demonstrates the click? Thanks

@ Dj Sures thanks for the fast response. here the video:  first you hear my mouse click, then the soundboard-click cheers Marty

Sorry, I need an example project so I can replicate the issue. If I cannot replicate the issue, I'm unable to know what I'm fixing. Hope that makes sense.

Smarty · Answer

now the example project is online and ready to download. I shared it with my old account name: "asimo"

DJ Sures · Answer

I will require a filename or a link to the project. Is it in the cloud? You can also upload to this forum using the attach file option.

I am having the same problem as Smarty, Getting "clicking" sound before speech starts. I don't have the problem with a ARC version from a few months ago. We had this problem awhile ago but I can't find the thread. I believe it was related to the Talk servo control. You fixed it DJ.

Here you go: https://synthiam.com/Community/Questions/9404 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.

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

DJ Sures · Answer

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
