"Directly playable" is a complex question - what are you assuming your web 
users have?

Browser only:           HTML 5 browsers mostly support Oggvobis natively
Browser+quicktime:      gsm,mp3,wav etc
Browser+flash:          MP3 (and perhaps speex)
Browser+java:           Pretty much any format you like....

I wrote (and opensourced) a little java applet that plays .gsm files
