Enter the bpm of the song you're working on and this calculator will give you the length in milliseconds for several note values.
Main use: To set your delays, pre-delays, reverb etc... It will also calculate the Hertz modulation for each note value too!
Great for settting modulation effects like Tremolo, Vibrato and... oh yeah, LFO's!!!
This 'note-from-frequency' calculator will help you find the nearest note (note-name and midi-number) from a frequency.
For example: 440 hz = A4
You might also find this useful to correct a slightly out-of-tune vocal or instrument within your mix if you're using, for example; Antares AutoTune or the pitch-shifter in Sonic Foundry's SoundForge, or whatever.
