a technical question

[peppy_man]

I would like to upload a sound file (WAV file).
Should I compress it to a ZIP file beforehand?
Is there any good tool for file compression?
Thank you in advance.

you really do not need to download a file on a special version.
there is a program called ( mp3 to wave) that changes the version of musics.
try this one.

Where are you trying to upload the file to?

Where are you trying to upload the file to?

To here.
I've written down a sound file (WAV file) of a TV program,
but there are some difficult parts in it.
I'd like native English teachers to correct it.
However, I'm not sure if I can upload a WAV file to here.
Should I compress it to a ZIP file?

[Q.E.D.]

WAV files are very large, because they are uncompressed raw audio data. You could compress them to a ZIP file, but then your audience would need the extra step of decompressing them in order to play them. You'd be better off to convert the WAV format to MP3; there are several freeware utilities available to do this. I suggest creating the MP3 with a minimum of 128 kbps sampling. This will allow a high degree of compression while still maintaining the integrity of the recording.
