![]() ![]() Some of them seem to work well and some of them don't, but I'm curious what you all have found. I made this post because there are literally hundreds of transforms available with all the various plugins. The program and all the plugins you can use with it are available for free at and can be run on Mac, PC, or Linux. For those who are unfamiliar with it, it allows you to take an audio file and perform a variety of useful transforms such as note and harmony identification, key extraction, and a number of spectrographic methods. It is also a good reference for mapping these drum kicks.This week in the sound design class we were introduced to the Sonic Visualiser audio analysis program. This is very useful if you are trying to detect BPM timing section of songs that have drum kicks. In this way the drum kicks is always quite visible even the song itself is quite "noisy".These two drum kicks should be 2 beats apart which means 60/188*2=0.638s. Let's focus on the lower part of the spectrum, which shows the drum kicks pattern(around 35Hz).This is showing the melodic range spectrogram of dimension tripper(Artist: nao). Using Sonic Visualizer to detect drum kicks Use the previous technique to define a BPM each note. You can see the notes are seperating more and more. This is the region that BPM is constantly changing. Try to find out the millisecond number of each note and calculate the corresponding BPM(beat-per-minute). Knowing which note is which sound, pulling out the timing is easy.First part forms a G#m7(G# - B - D# - F#) chord, or VIm7 chord. You can actually find individual notes if the song is "clean" enough. On the left there is a frequency axis which indicates the pitch. ![]() The dark blue light indicates the notes of this song. This shows the melodic range spectrogram of this song.
