Replaced queue-youarenext.ulaw and queue-thankyou.ulaw

Good morning everyone, I went ahead and replace queue-youarenext.ulaw and queue-thankyou.ulaw with a custom recording. It works but I hear a squeaky noise before it plays the recording. Here is the recording. Please go here to listen to the audio sndup net /cn92/

I was wondering if there’s anything that could be done? I’ve used the following tool, bitrate is 128kbps
toolslick com conversion/audio/wav-to-ulaw

The file you posted is stereo. Your custom recordings must be mono, 8 kHz sampling rate.

These are the settings I have when I export the .wav to ulaw
Channel is set to mono

If you don’t see an option for 64 kbps, use a different converter.

I used Audacity and exported the .wav file to ulaw with mono and 8kHz with 64kbps. The squeaky noise can still be heard.


Asterisk µ-law files must be raw µ-law fles, without the .wav RIFF header. Alternatively you can use 16 bit linear (so 128kbps) with a .wav file name extension.

The squeaky bit is probably the result of treating the .wav (RIFF) header as audio.

You are correct, the file needed to be saved in the following way in order for the squeaky noise to go away. I no longer hear the noise! Thank you so much David. Here’s the final audio without the noise.
