AtsFile
Extension
ExtensionDescription
ATS (Analysis-Transformation-Synthesis) files are analysis files created using Oscar DeLiscia, Juan Pampin and Pete Moss's atsa command-line analysis tool (available at http://www.dxarts.washington.edu/ats). The analysis of the sound first attemps to track and record frequency data into sinusoidal partials. Then, any sound that couldn't be analyzed into partial information is analyzed as noise information. The information can then be tranformed and resynthesized using this information.
Once installed, type atsa at the command line to see flag options and usage.
An example from within the SuperCollider_f directory:
atsa sounds/a11wlk01.wav sounds/a11wlk01.ats -H5000
-H5000 limits the analysis to frequencies below 5kHz.
Class Methods
.new
Load an ATS file into memory at path with buffer number bufnum. server defaults to Server.default.
Arguments:
| path |
Path to the ats file. |
| server |
Server. |
.load
Loads the information of the ATS file into a buffer for use by the AtsSynth UGens. If buffer is nil, one will be allocated for you. Only for real-time usage.
Arguments:
| path | |
| server |
Instance Methods
.data
.load
Loads the information of the ATS file into a buffer for use by the AtsSynth UGens. If buffer is nil, one will be allocated for you. Only for real-time usage.
Arguments:
| buffer |
Buffer to use for loading the ATS file. |
.frameSize
.saveForSC
Save the ATS file as an AIFF that can be loaded into a buffer (for NRT and fast loading file data in real-time)
Arguments:
| path |
Path to the saved file. |
