This depends on the codec your users are using.

If its PCMA or PCMU then you should be fine with wav, and if you want to suppress the 2 channels message you can convert it to a mono file, here's an example with sox.

sox input.mp3 -c 1 -r 8000 output.wav

Hi,users.

I have 1-100 sound files (mp3) and wants to play these files in loop from 1 to 100 to more than 250 concurrent users. 

Currently these sound files have format.

Codec: MPEG audio layer 1/2/3 (mpga)

Channels: Stereo

Sample Rate: 22050 Hz

Bitrate: 64 kb/s

While playing these files I see in freeswitch log.

2015-04-23 14:17:59.351859 [WARNING] switch_core_file.c:230 File has 2 channels, muxing to 1 channel will occur.

I want my freeswitch to have minimum load while playing these files (located on freeswitch server).

I which file format I must convert these files to have my freeswitch  with  minimum load.

Your Guys opinion is much appreciated.

Thanks
