++ The Rhythm Ferret is a dedicated tool to speed up the usually labor intensive + task of slicing and adjusting a sound region to match a specific time grid. It is + especially useful for drum tracks, either to match a different tempo, or to + adjust a slightly out of tempo performance. +
++ It is not limited to this use though, as it supports both percussive and note + type detection, and can be used on melodic material too. +
+ ++ The Rhythm Ferret window can be accessed by Right clicking + any audio region, then Name_Of_The_Region > Edit + > Rhythm Ferret. +
++ Once the window is open, selecting any region will make it the focus of the + Rhythm Ferret's detection, hence allowing to process multiple regions sequentially + without reopening the window each time. +
++ The window itself is made of: +
++ As the Rhythm Ferret is able to detect both percussive hits and melodic notes, + it is important to choose the best suited mode for the considered material, + so that Ardour can perform the detection with the greatest accuracy : +
++ In this mode, only two parameters are active: +
++ As those parameters are very material-related, there is no recipe for a perfect + match, and a good peak detection is a matter of adjusting those two parameters + by trial and error, and trying using the Analyze button + after each try. +
++ Vertical grey markers will appear on the selected region, showing where Ardour + detects onsets as per the parameters. This markers can be manually adjusted, see + bellow. +
+ ++ In the Note Onset mode, more parameters are active: +
++ The Detection function, used in Note Onset mode to choose the mathematical strategy + used to detect the note changes, is user-selectable: +
++ Ardour defaults to Complex Domain, which usually gives good result for harmonic + material. +
+ ++ Using the Rhythm Ferret consists usually in finding the right parameters to + split the audio, by adjusting them and clicking the + Analyze button. Each time an analysis is run, Ardour + erases the previous results, and creates grey markers on the region according + to the parameters. Those markers can be manually dragged with the + LEFT mouse button to adjust their positions. +
+
+ Once the markers are suitably placed, the second button in the down hand side
+ of the Rhythm Ferret window allows to Apply the operation.
+ At the moment of writing, only the
+ Those regions can then be manually aligned, or have their sync points set to + the closest grid (as per the Grid settings in + effect), by selecting all the regions, and using the + RIGHT click > Selected Regions > Position > + Snap position to grid. +
