what is the configuration for minimum memory size for recording

[dor]

hello,

i use sansa clip+.
and i want to set the best setting for recording lectures(minimum memory size for recording and still
that the sound will be ok, the format can be mp3 or wav) .

what is the setting for this case?

thanks.

MP3 will be smaller than WAV, so if you want small file size use that.  For voice the bitrate probably doesn't matter.

WAV is mostly meant for recording actual music.

How low can I download the frequency?
The bitrate I will choose will be the lower that i can set.
I want to record a two  lecture speech, the file size i expect to get
is about 20 MB.

thanks
