Hi,

with the help of Strikers tutorial on youtube https://www.youtube.com/watch?v=2lcL6ZPU4EE
I was able to create a soundboard and everything works so far.

I only have one problem. When pushing an audio button, the audio is played immediately but the first second is always a silence.
The audio length for each uploaded audio is always one second longer than the original audio file. My reference is the counter which appears after an audio button is pressed.
The original audio files do not have this silence of one second at the beginning.

Is this normal? If not, how can I fix this?

Normally it will play instantly, but we need to make sure if there is lagging issue with network or phone connections with server.
if you can share your playback log with asterisk so I can check if there is any other process running before it which is generating this delay.
please share asterisk log for this playback if possible.

Thank you for the response. Here the cli when pressing an audio button:

Hope this helps.

Hello, From logs it looks proper processing for the audio file, so might be delay due to lagging of network, are you using same network where this server is located or server is on remote location?

I am using the same network where server is located.

[martinch]

Oh hey,

Log looks normal and clean. Few things from my end;

• Can you try capturing a call recording and verifying the delay exists there too.
• Is there a delay in the agent hearing the sound or the caller?
• I know you said you trimmed the audio...might be worth checking again. Check the waveform in Audacity.

That's all I had for now cheers, Martin.

Hi

Can you try capturing a call recording and verifying the delay exists there too.

Yes, delay is also in recording.

Is there a delay in the agent hearing the sound or the caller?

Both

Check the waveform in Audacity

Checked, it is .wav 8000 khz, 16 bit mono.


When I press the audio button on my avatar, a counter starts counting down the length of the audio. But the length is always one second longer than the original file. This one second is the "silence second" at the beginning.
