Audio Quality Issues while playing back audio files
Hi, I have been trying to play mp3 and wav files using freeswitch but noticed that the audio quality of these files are degraded. After looking for a while on logs, I think the sampling rate of these files goes down to 8K as I see “Codec Activated L16@8000 1Channels 20ms” in the fs_cli log… How can I retain the audio quality (sampling rate) of these files ? -- Regards, Bharath Pareek
Are you using a wideband codec? Most telephone codecs use a 8000 rate so you'll get that drop. On 17 October 2013 16:15, Bharath Pareek <bharathpareek@gmail.com> wrote:
