Expand a single analysis window over time, freezing the sound. EXPAND creates a single expansion at time secs. over dur duration, while in HOLD you specify a list of times and hold-durations. Compare with SPECFREEZE and STEPFREEZE. EXPAND Extract a single analysis window (spectrum) at time seconds and expand it over dur seconds. Note that dur is the output length. PARAMETERS time Time in the file where the single window to expand occurs. Range: 0 - file length (secs.)
dur The
output file
length; also how long the spectral analysis window is held
for.Range: >0
-
any value (secs.) Must be > analysis window-length.
HOLD Hold the sound using a list of times and hold-durations. Like EXPAND, HOLD time-expands the spectrum found at time., but here the expansions occur in the original file, which is lengthened. PARAMETERS datafile of pairs times and durations. After the duration period, the "hold" is released, until the next time occurs. (The last
time
must be less than the file-length.)
Example:
time duration 0.5 0.5 1.5 0.5 2.5 0.5 3.5 0.5 4.5 0.5 NOTES EXPAND creates a static sound out of a single moment. HOLD is like musical tenuto: it is important to find interesting times where the spectrum might be held. One use is in conjunction with GLIDE, whose transition stops at the end of the output file; it is more natural to HOLD the final sound for a short time.
