Researchers, and anyone else looking for a friendly way to look It'sĭesigned for musicologists, archivists, signal-processing Reach for when want to study a music recording closely. Windows, Linux, and Mac, designed to be the first program you I think the ScratchTools one might be a good idea.Sonic Visualiser is a free, open-source application for I will have a look at all these things and see what works best. for his new one, he uses a special application called scratch tools Must be this one: - Thanks everyone for all the help. CloudGate- wrote:colorgram has some projects that in the notes and credits explain how the data is received. I'm not going to do it that way, but knowing audacity can do part of it might make it possible to import it a different way. I was actually looking at the Audacity tools and thought about cutting out the frequencies, but it never occurred to me that I could use the loudness block on Scratch to get the data imported. (scratchtools comes close and is what I use in Music Visualizer Y, linked above) For the bass boost - it's just a separate bass only track that plays at the same time and its volume gets switched on/off. Unfortunately, you can't automate this process. If you decide to do this you will probably have to process the tracks in audacity before playback since you want scratch to record a good range of loudness values (eg not always 0, but not always 100). Very straightforward, though of course you will need to be familiar with audacity, storing data to and reading from a list in scratch, and be comfortable using the ‘timer’ in scratch. You will need to do this 8 times for all 8 bands, with accurate timing (now you see how tedious this is) This project then just takes those lists and draws bars for each of them. Then, you just need to record your computer playing each of those frequency bands while scratch records the ‘loudness’ values into a list using a microphone. (For this project, I used: 0-50Hz (band 1), 51-99Hz (band 2), 100-200, 201-500, 501-1000, 1001-4000, 4001-10k, 10k-16k (band 8)) Now, each of the 8 frequency bands represents a slice of the full song - with lower bands containing the low frequency data (bass), and the highest bands containing the high frequency data (treble). How you decide where the cutoffs are is up to you, but your lower and upper bounds should be around 30Hz and 12KHz.

For this project, I split a song into 8 ‘frequency bands’ (sort of like colors of a rainbow) using the low/high pass filters in Audacity (open source software).

There is an explanation on : Quite a few people asked how this works so hopefully this will help you understand: All sound is just a collection of vibrations with different amplitudes at different frequencies (Hz).
