[Freeswitch-users] mod_shout and mp3 formats

[Peter P GMX]

I try to play mp3 I generated through Cepstral TTs and which I encoded
via lame.
However they won't play, so my question is: Which mp3 formats are supported?

I generate the wav files by the following
/opt/swift/bin/swift -n Katrin -p
audio/channels=1,cst/f0_shift=.8,speech/rate=120,audio/sampling-rate=8000,audio/deadair=2
-o $wavefile $text

Then I convert to mp3 by the following variations:
lame 46.wav 46.mp3
lame -s 32 46.wav 46.mp3
lame --preset 128 46.wav 46.mp3
lame --resample 44.1 --preset 128 46.wav 46.mp3
lame --resample 32 --preset 128 46.wav 46.mp3
lame --resample 44.1 46.wav 46.mp3
lame --resample 44.1 -m s --preset 128 46.wav 46.mp3
lame --resample 44.1 -m s  46.wav 46.mp3
lame --resample 44.1 -m s -b 128 46.wav 46.mp3
lame --resample 44.1 -m s -B 24 46.wav 46.mp3
lame --preset voice -v -B 64 -a 46.wav 46.mp3

None of them worked with the playback application
(shout://localhost/tts/46.mp3). The sound files had a length of between
2 and 5 sec. 2 Times during various tries they played at least
partially. But at the next try they didn't play again. However I have a
prerecorded sound file (44.1KHz, 128 kBits stereo music) which always
plays well.
The console shows me that all files are successfully played and I get a
channel_ececute and a channel_ececute_complete after some seconds during
event_socket. But I don't hear any sound.

All above samples however played well with Totem on Ubuntu.

The wiki tells me that almost any mp3 format should play. What am I
doing wrong here?

Another question: Should normal wav files play as well? Also with wav I
cannot hear any sound.

Best regards
