I remember being able to change the project’s bitrate while editing it a few years ago. After an update the only way to change bitrate is to export the file. Is there a way to bring this back? It was in the bottom left.
Tracks → Resample.
FYI - That this is the sample rate (usually kHz) which is the number of times the waveform is sampled on one second.
Bitrate is the number of bits per second (usually kbps) and it’s an indication of file size (along with playing time). It’s normally used as an indication of the amount of compression with loss formats like MP3.
There are 8 bits in a byte so although we don’t normally talk about the bitrate for uncompressed files, we can can calculate it: CD audio is 16-bits (2 bytes) per sample at a sample rate of 44.1kHz, and it’s 2-channel stereo. 16 x 44.1kHz x 2-channles is 1411 kbps. Or, that’s 2 bytes x 44.1K x 2 channels = 176k bytes per second, or about 10MB per minute. (That’s ignoring any embedded artwork which adds to file size without affecting the bitrate.

Is that 176 kilobytes or 176 kilobits? The nomenclature often confuses me. I’m from back in the day where a kilobyte is 1024 bytes and everybody measured it that way.
Bytes. Divide the 1411kbps bitrate by 8 bits per byte.
It seems to depend on the context whither 1KB is 1000 bytes or 1024 bytes. (Wikipedia).
Unless you are designing digital circuits or writing low-level code it usually doesn’t matter. If you have memory chip with 10 address bits, or a 10-bit address bus, you can “count to” 1024 memory locations. (Actually you can only “count to” 1023 but there is an address at 0 so you can store 1024 values.)
I remember a long time ago reading that hard drive manufacturers were using the “decimal” values based on 1000 so the specs look better.
OFF TOPIC - There are 8-bits in a byte and 8-bits in a dollar. I remember my dad saying “2-bits” for 25 cents. That never made since (no pun intended) because how could you ever have 12-1/2 cents??? But not too long ago I was reading some history about money (when it was silver or gold). There were half-dollars, quarter-dollars, and eighth-dollars which was one bit! Perfectly logical if you’re using fractions instead of decimals!
