for batch processing, you can use the Convolution module (Ctrl+L) of FScape ( http://sourceforge.net/projects/fscape ) along with the Batch Processor (Ctrl+9):
- configure the convolution module (your recording goes in "Input file", the time-reversed sweep in "Impulse response") - press "Add" in the batch processor. Click on the "Command" column entry of line 1 and choose "Begin loop" from the context menu. - press "Add" again, from the "Command" column entry of line 2 choose "Module" (if there is more than one module open, choose the convolution module in the dialogue) - press "Add" again, tfrom the "Command" column entry of line 3 choose "End loop". - then make sure your file names have a common incremental number in them, click on the "Line 2" of the batch and look up the "InputFile" field in the lower part of the window, replace the common incremental number in the "Value" column with the loop variable ($A).
- hit "Render"x = SynthDef( \sweep, { arg lowFreq = 20, dur = 20, amp = 0.5; Out.ar ( 0, SinOsc.ar( Line.ar( 0, 1, 20, doneAction: 2 ).linexp( 0, 1, lowFreq, SampleRate.ir / 2 ), mul: EnvGen.ar( Env.linen( 0.05, dur - 0.1, 0.05, amp ))))}).play;
