object RecordBuf extends ProductReader[RecordBuf] with Serializable
Records input into a Buffer. If recLevel is 1.0 and preLevel is 0.0 then the new input overwrites the old data. If they are both 1.0 then the new data is added to the existing data. (Any other settings are also valid.)
Examples
// record and replay // a four second mono buffer val b = Buffer.alloc(s, s.sampleRate.toInt * 4) // record for four seconds play { val sig = Formant.ar(XLine.kr(400, 1000, 4), 2000, 800) * 0.125 RecordBuf.ar(sig, b.id, doneAction = freeSelf, loop = 0) } // play it back play { PlayBuf.ar(1, b.id, doneAction = freeSelf, loop = 0) }

- in
the signal to record
- buf
the identifier of the buffer to use
- offset
sample frame to begin writing from. This is read when a trigger occurs.
- recLevel
value to multiply by input before mixing with existing data.
- preLevel
value by which the previous buffer contents is multiplied when recording. If this value is zero, the buffer contents is completely overwritten. If this value is one, the new signal is added to the previous content.
- run
if zero the recording pauses, otherwise it resumes. The value of run is only read at control-rate! When the recording is paused, the "write-head" remains in its current position and does not advance.
- loop
1 to loop after the write head reaches the buffer end, 0 to not loop. This can be modulated.
- trig
a trigger which causes a jump to the given
offset. A trigger occurs when a signal changes from non-positive to positive (e.g. <= 0 to > 0).- doneAction
what to do when the write head reaches the buffer end. This is only effective when
loopis zero.
