Around 2007 I found Moodlesppex a java applet that would:
- record voice message
- compress the audio into the speex codec
- upload the audio
I ported it to wordpress around 2007 (source code lost to history :( ).
I looked at adobe flash when I found out it supported speex codec, but at the time I all them need a RTMP server to capture the audio.
- voice email
I remember plugins/addons for email clients that would allow you to record a message attachment(?) I dont remember what audio codec they used (ADPCM?, realaudio?)
I also remember a application that would allow you to record a message
