Re: [Zope] any streaming audio formats that Zope can serve?

MP3 streams very well. eg http://www.icecast.org and http://www.shoutcast.com And there are free versions of decoders and encoders. http://freshmeat.net
Played a bit with this - mp3 is expensive to encode, and also isn't all that great for compression for the data I have. The data I have is 12 bit 6kHz sound samples, and it's necessary to convert it to a much higher resolution format to use it with MP3.
Realaudio also streams pretty well over http.
I need to be able to convert data on the fly - unless things have changed, the realaudio sound format converters are expensive, and just not very good. Current plan is to play with using the Quicktime4Linux library to stream the data. I'll post more when I have had more of a play. (For those that are interested: the application in question is to allow a user to browse a voice message box, and select voice messages to play. It currently delivers a .wav file (generated by an external method) and the browser downloads it before playing...

I have been using jfax for FAX and voice messages. Really cool. You can have a virtual office in many big cities around the world that accept both fax and voice messages that get sent to up to 3 email addresses as attachments. The FAX is tiff format. The voice is GSM by default and jfax provides a free recorder/player. { see http://www.jfax.com } It handles these formats: *---Quote from help: "GSM is the worldwide standard for quality and small file size of audio files. WAV is the standard file format supported by Windows (PCs) operating systems. WAV files are typically 5 - 10 times larger than GSM files. AU is the standard file format on most UNIX operating systems. " Maybe GSM would work for you. PS: I have no connection with jfax other than as a user. You can have your own free FAX or voicemail number or you can pay for extra features and location of your "office". -BobO Connor bob@rocnet.com ----- Original Message ----- From: Anthony Baxter <anthony@interlink.com.au> To: <zope@zope.org> Sent: Tuesday, July 13, 1999 8:33 AM Subject: Re: [Zope] any streaming audio formats that Zope can serve?
