Can I make it even smaller?

Hi guys :slight_smile:

I have a 14 seconds sample that I’ve sampled down to a 16 bits mono at 44100hz. The file reaches 218kb in size and the sound quality is still good.
Now the question is : can I make the file size even smaller? How?

I’ve tried to change it to 22050hz and then fix the speed with the effects but then, the 22050hz version is still 218kb, just like the 44100hz version.

Does it mean that there is no way I can make it smaller?

Thanks for the help :slight_smile:

You didn’t change the sample rate to 22050Hz, because you didn’t change the Project Rate control at the bottom of the screen. You changed the sample rate of the data in the project, then converted it straight back when you exported because you didn’t change the project rate.

To actually export at 22050 Hz, you need to take the original, open it in audacity and change the project rate to 22050Hz. This will cut off all frequencies about 10kHz in the saved file.

Much more effective to get more audio in less space is using a lossy compressed format like Ogg Vorbis. This does depend on what you are going to with the file, and if the recipients can cope with files in that format (but the same applies to unusual sample rate wav files).

Hi Richard :slight_smile:

Thanks for the info. I finally managed to resize it to 100kb.

Have a nice day.
