object RecordBuf extends 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 loop is zero.
