smtool - tool to show/change SpectMorph data from .sm/.smset files

smtool <sm_file>|<smset_file> <command> [ <command_specific_args> ]

smtool is a general purpose program that can perform operations on .sm/.smset files. Some of the operations extract data (like size), others modify data (like auto-tune). If a .smset file is given as argument, the operation is performed on the individual .sm files that are contained in the .smset file.

smtool options depend on the command used, the command specific arguments are listed below.

volume <percent>
Compute average energy of the audio data around <percent>.
fundamental-freq
Output fundamental frequency of the audio data.
mix-freq
Output mixing frequency (sample rate) of the audio data.
zero-values-at-start
Output zero-values-at-start property of the audio data.
attack
Output attack parameters of the audio data.
size
Output overview of the size in bytes of the different parts of the audio data.
loop-params
Output loop parameters of the audio data.
noise-params <frame_no>
Output noise component of a frame of the audio data.
frame <frame_no>
Show original samples and reconstructed samples for one frame of the audio data.
frame-params <frame_no>
Show the freqencies/magnitudes of one frame of the audio data.
total-noise
Sum up all noise parameters of all frames of the audio data.
nan-test
Check all frame data contents for NaNs.
original-samples
Show original samples of the audio data.
freq <freq_min> <freq_max>
Show all frequency entries of the audio data in the specified range.
spectrum <frame_no>
Compare original and reconstructed spectrum for a given frame.
auto-loop <percent>
Set a one frame loop that starts and ends at the same point (given by <percent>).
tail-loop
Loop audio data at the end using a one frame loop.
auto-tune
Tune instrument using the (40%..60%) data to extract the actual frequency.
tune-all-frames
Tune each frame of the instrument. This will discard minimal changes in frequency which are normal for most instruments, so it might sound artificial.
auto-volume <percent>
Normalize audio volume, using the volume around <percent> as reference.
auto-volume-from-loop
Normalize audio volume, using the volume of the looped part as reference.
