Monday, April 20, 2009 Basic review of Audiosculpt Preferences --- set new home folder and sound folder for audiosculpt outside of application folder FFT analysis window size larger the window size the better the frequency analysis and the poorer the temporal resolution FFT analysis, window size, hop size added "markers" to a sound file "generate markers" Marker Analysis Parameters Transient Detection Settings Threshold (trial and error, but lower the number the greater the sensitivity i.e. more markers) markers can be added and deleted In audiosculpt one marker appears but there are two markers (one invisible) onset outset... use SDIFConverter to get text file of start times or end times of export makers.sdif All data is exported as SDIF go to Audiosculpt/SDIF Utilities for converting SDIF files to text files SDIFToText (drag and drop file on top of this) -- this gives complete view of SDIF contents (not friendly) SDIFConverter (independent application double-click) choose what you want to see Audiosculpt/ChordSequence Open Music open new patch File/new patch click in space while holding "apple" key type in --> sdiffile click on object to highlight (dark boarder keystroke -- v (opens window to locate sdif file) load soundfile.mrk.sdif (generated from the audiosculpt marker tool) letter b to lock sdiffile LOAD LIBRARY windows/library/user libraries/repmus touch bottom part of suitcase and double click click in space while holding "apple" key --> sdifinfo evaluate sdinfo to see contents of SDIF file keystroke -- d (opens short text file documentation) click in space while holding "apple" key --> get-times go to functions/user libraries/repmus/audiosculpt shift click on input buttons of object to add boxes get-times needs sdiff information stream number and data type FIRST INLET == OUTPUT OF SDIFFILE SECOND INLET == STREAM NUMBER 0 THIRD INLET == FRAME SIGNATURE == "1MRK" FOURTH INLET == 1BEG (to take the beginning of each marker as Audiosculpt markers have start and end points) DOCUMENTING YOUR PATCH: control click and select comment to add a comment box into your patch Markers are in seconds --------------- jump back to Audiosculpt open markers and apply chord sequence analysis save as SDIF file open this in Open music with sdiffile window-libraries user library add repmus library double click in bottom part of suitcase (not top of suitcase!) repmus library is installed go to OM and functions/userlibrary/repmus/audiosculpt/AS->OM first inlet == analysis from SDIFFILE second inlet and third inlet == amplitudes as midi velocities fourth --delta == integer, onset time falling with the window of 1/100 of value in milleseconds mmin == minimum pitch midi cents mmax == maximum pitch in midi cents microtonal approximation in half-steps (2), quarter-tones (4), eighth tones (8) npoly == number of polyphonic voices v == evaluate (any object) midi path in open music chord seq --> midi---> midishare-->quicktime OM object sound shift select chord seq and shift select chord to play a sound file and midi realization at same time
