Poor Caller Audio Quality

04/15/2025, 2:53 PMWhy does the caller's audio sound so muffled and poor when listening back to the audio recording of the conversation between the AI and the caller?
I've tested this on many different microphones and web/twilio, and it all sounds muffled and low-quality.
Any ideas? Is it the Transcriber which affects this or what? No wonder the transcriber struggles to convert to text when the audio is dreadful.

04/15/2025, 6:47 PMAny suggestions on how improve input quailty? Tried various microphones ranging from a headset to a blue Yeti. Even calling via twilio on my mobile phone when i review the audio it sounds damp and muffled. Wasn't sure if there was a setting or if it was related to the transcription model?

04/16/2025, 8:03 AMTried with two, one a landline and one a mobile - plus this test wouldn’t make sense as I’ve also tried it on the web via my microphone on the vapi dashboard
