[Freeswitch-users] Best sound file format for freeswitch

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

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

also, if you want the minimum possible load, mod_native_file (compiled by
default) lets you use audio files in native format (eg: in PCMU format, or
whatever codec you happen to use):

yes, go from stereo mp3 to mono with one only pass. You can use sox, lame,
audacty or whatever, but probably the easiest and bullet proof way is to
load mod_shout in fs_encode, and use it as per mod_native_file confluence

Then use local_stream, then your load is no longer a concern! Its one file,
one decode, copied to many clients.

Still doesn't matter, If you have 100 files you wish to pay in sequence to
all the callers, the same applies. Its still one local string with a list
of things to play and its shared to all callers.

WAV is best if you have several callers with varying codecs. Its stored
decoded and only has to encode and PCMU for instance from SLIN is not very
costly.
Ideally you want to match the rate and number of channels that most callers
will have.

WAV is best if you have several callers with varying codecs. Its stored
decoded and only has to encode and PCMU for instance from SLIN is not very
costly.
Ideally you want to match the rate and number of channels that most
callers will have.

Brain i think what he's trying to say is that he'll have upto 250
callers, that can call in at any time, and when a caller calls in, they
need to start at the beginning of this list, not where the stream currently
is.

Still doesn't matter, If you have 100 files you wish to pay in sequence
to all the callers, the same applies. Its still one local string with a
list of things to play and its shared to all callers.

Hi, Brian.
I think you misunderstood my question. Its not one file but 100 files
that we are playing in sequence(1-100) to every Caller.
Thanks

Yep, We are playing same sound files to every user. Actually sound
files are some sort of lecture files. As soon as a call comes in, we start
playing files from 1 to 100.

Thanks for your quick reply.
Does suppressing 2 channels would be helpful?

yes, go from stereo mp3 to mono with one only pass. You can use sox,
lame, audacty or whatever, but probably the easiest and bullet proof way is
to load mod_shout in fs_encode, and use it as per mod_native_file
