Audacity Forum

I'm interested in writing an audio editing app, and therefore interested in how the timing grid in modern daws is implemented efficiently so that the UI is responsive and calculations related to the timing grid are quick. My interest includes: Drawing and labeling the grid lines for measures, beats,...

ideally (IMO) a Click Track generator would have an option to simultaneously generate labels at the beats (or bars). Currently Nyquist plug-ins can only return one "result". We can have a plug-in that returns a click track. We can have a plug-in that returns labels. We can't currently have a Nyquis...

Yes, I would just like it as an option. I'm not wanting Audacity to be a sequencer or a DAW. My desire for bars|beats timeline is for editing a single audio file. Ex.: I have a four minute wav file open in Audacity, and measures 31-39 need a revision. I know its tempo is a constant bpm of 142. So he...

I can't find this in the Audacity application or in any of the forums, which strikes me as strange because it seems rather fundamental: I'd like to request that the timeline, currently only available in min:sec, to have an option of showing bars and beats. One would have to know the bpm of a piece o...

I've used the above submitted code to "filter" out some prominent beats in the following example The original loop is at the beginning. This loop is then analysed at 12000 Hz (that's made with "reson"), this leaves kick and snare (the high pitch of beater and stick are found). The third part holds t...

Hello, We want to save the time values when the sound wave rises above the input threshold value & falls below the threshold value so as to locate the beats. Please can you help us with the nyquist coding . As our main aim is to caculate beats per minutes for which we have added a new plugin in Auda...

Have you seen my recent plug-in "Tempo Teller"? The current version is: rjh-tempo-teller.ny I've decided not to work with single sample values. If you wanna do that, you should resample the audio track. My algorithm is roughly as follows: - take 30 s, resample to 51200 (100* 2^9) - create a curve, f...

Using Audacity 2.0.5 in Windows 7 Ultimate. I have an audio track that's missing a snare drum on the off-beat. I downloaded a sample snare hit, imported it into Audacity and lined it up to it's first occurrence by ear. Then I Duplicated the snare sound and pasted it onto the end of the original one ...
