First, mp3 is patent encumbered. Also it seems most patent enforcement is aimed at the encoders and not the decoders. Much like the way WMP and Real work, those producing content can afford to pay for the work. Second, read the rants on licensing. Unless you find a BSD licensed mp3 encoding library and convince Mark of it's need, it is unlikely to make it to the core code base. Third, those complaining of low volume in emailed files are usually using a compressed format. In the uncompressed wav format, the volume is effectively doubled by shifting the audio data to the left one bit. This is done at the format level. Of course on playback via asterisk, it checks to see if it needs to shift the audio down and does so. So playback between asterisk recorded wav files should all sound the same on asterisk but isn't the same when played via a normal audio app. I wouldn't mind seeing someone place a audio adjustment in the voicemail app and make it adjustable. Then remove what I suspect is a crude hack in format_wav.c > But I digress....I'll dive in and snoop around format_wav_gsm anyway. -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
