is there a way to change the bitrate of a song on audacity? I am doing a science fair project where I need to change the bitrate and the website said to use this, but I cant find a way to change the bitrate. please help me! I am using version 2.0.3 and I don’t know what I installed it from.
If you are talking about exporting MP3 files, choose “MP3 Files” when you export, then click the “Options…” button to adjust the MP3 export bit rate.
If you are talking about some other format please tell us the exact file format and export specifications you want.

How do I export a wav file at a different bit rate. I only see an option of 16bit and I need 24bit. I have version 2.0.2. This is due tonight so if someone could help me before then, that would be hugely appreciated. I’ve looked through the threads and can’t find the answer. 
Thanks so much!

Select “other uncompressed formats” in the Export dialogue. http://manual.audacityteam.org/o/man/file_export_dialog.html

You are confusing the terms… If you tell us a little more about your experiment, maybe we can help.
Bit Depth is the number of bits in each sample. (8, 16, 24, 32).
Sample Rate is the number of samples per second (kHz). CD audio has 44,100 samples per second, or a sample rate of 44.1kHz.
Bit Rate is the number of bits per second (kbps). This is most-often used with compressed files to get an idea of the amount of compression or the quality. If you know the file size and the playing time, you can convert bytes to bits (8 bits per byte) and calculate the (average) number of bits per second.
Or, You can calculate the bitrate for uncompressed audio if you know the number of bits per sample, the number of samples per second, and the number of channels. CD audio is 16 bits x 44.1kHz x 2 channels = 1411kbps. That’s about 5 times the bitrate (and 5 times the file-size) of a good quality MP3.
Thanks Steve! That’s what I needed.
