How to zip a file in audacity

Im currently using windows 8 and audacity version 2.0.5 and Im trying to zip the file I created to a pretty small size but its not letting me. I have to save it as a .wav file and its current size is 1,056KB and I was able to zip it to the following size (763KB) but its still too big to transfer… how can I make it smaller???

Is the work required to be in Stereo? If not, you can save half the filesize right there by converting to mono. If it’s a spoken word show, nobody will miss it. Nobody wants to whip their head back and forth as people speak. I wonder about making a ZIP and having the file shrink that much…

If that’s still too big you can do what billions of other people before you have done and create an MP3 instead of WAV. If you pick a super good quality MP3 (256 for stereo and 128 for mono). nobody will be able to hear the difference. The only problem with that is you can’t easily open it up and edit it after you do that. MP3 makes terrible archives. It’s only good for final delivery to a Personal Music Player or internet posting.


Transfer it in several different WAVs.

There’s FLAC. That’s a loss-less compressed format that can shrink files without losing anything, but you have to know how to read it at the other end. They’re not WAVs.

Interesting… That’s in the same ballpark as FLAC & ALAC (lossless audio compression formats). FLAC & ALAC will typically reduce the file to about 60% of it’s original size. (FLAC & ALAC are optimized for decoding on-the-fly for audio playback.)

As Koz says, with MP3 or AAC (lossy audio compression) you can do better. You can typically make a file about 1/5th of the original size with good (or excellent) quality, and even smaller if you are willing to accept more quality loss.

With WAV files, the file size depends on the playing-time of the file, the sample rate (kHz number of samples per second), the bit depth (the number of bits per sample), and the number of channels. You also need to know that there are 8 bits in a byte.

A “CD Quality” WAV file is 44.1kHz, 16-bit, 2-channel stereo. For example we can calculate the file size for a 1 minute CD quality WAV file as follows:

(60 Seconds) x 44,100 x (16/8) x (2 channels) = 10.06MB

For compressed files, we can calculate file size if we know the bitrate. The bitrate is normally given in kpbs (kilobits per second). So, it’s easy to calculate file size as long as we remember there are 8 bits in a byte. For example, A 60 second file at 256kbps is:

60 x (256,000/8) = 1.920 MB

You can also calculate the bitrate for a WAV file. A CD quality WAV file has a bitrate of 1411kbps.

Open Winrar and choose the file to compress alternatively choose the file with mouse right click → Winrar menu → add to archive.
Within Winrar in “General” menu look down there is the option to “split to volume size” click in the field and choose the maximum size you want and next to it you choose the measure unit, in your case you choose KB, then there is an option (optional) to create a self extracting archive so you check the box “create sfx archive” then press ok and you’ll have you file audio splitted in several parts.

There is another program that does the same job, HJ-Split, it’s free and doesn’t require installation:

you’ll have you file audio splitted in several parts.

Oh, right. So this is the send multiple files scenario.
