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 Peter
