I have just compressed a file( radio interview) to 688kb, what size is it?

Question

I have a radio interview in wav, that was 54mb in size, far too big to upload to a site, have now compressed it to, 688kb's, after the kb's its in brackets saying 700,906 bytes, has this file really compressed that much? if so how much?

Answer 1

That's rather a good ratio. Voice is known to compress very well, ( one page I found says Speex gets 28:1 )

Still:
54*1024 = 55,296kb
55,296/28 = 1,948kb

Assuming the coded downmixed stereo to mono:

1,948/2 = 987kb

So 688kb is not completely out of the question, especially if the original file was at a higher bitrate than the ones used in the linked example.

Answer 2

it is 688 kbs and 700906

computers use a base 2 counting system
one kilobyte is 1024 bytes.
so 688kbs=704512 bytes.

( so its 684.478515625 plus some slack space ( it has to do with the way computers store files)

if you wanna know, look up clusters and slackspace

Answer 3

0.0012% of original size
