The folder CAMO-AIS_SWEVO contains the following 5 (five) subfolders, CAMO_Iowa, CAMO_Phil, CAMO_RWC, CAMO_SOL, and Listening_Test. The contents of the folders are briefly described below. CAMO_Iowa: Audio and Data for the orchestrations with the Iowa sound database. CAMO_Phil: Audio and Data for the orchestrations with the Iowa sound database. CAMO_RWC: Audio and Data for the orchestrations with the RWC sound database. CAMO_SOL: Audio and Data for the orchestrations with the Studio Online sound database. Listening_Test: Perceptual similarity ratings from the listening test found at http://http://camo.inesctec.pt/. This data is anonymous (each participant is assigned a reference number) so the participants cannot be identified. Each CAMO_* folder contains 2 (two) subfolders, Audio and Data for the CAMO algorithm used to generate orchestrations (AIS, GA, Orchids) with the respective musical instrument sound database. For example: CAMO_Iowa/Audio/AIS: Sound files (.wav) for the reference sound and the orchestrations generated with CAMO-AIS on Iowa CAMO_Iowa/Audio/GA: Sound files (.wav) for the reference sound and the orchestrations generated with CAMO-GA on Iowa CAMO_Iowa/Data/AIS: Data files (.mat and .txt) for the reference sound and the orchestrations generated with CAMO-AIS on Iowa CAMO_Iowa/Data/GA: Data files (.mat and .txt) for the reference sound and the orchestrations generated with CAMO-GA on Iowa The same structure applies to all CAMO_* folders. Note that only CAMO_SOL contains a subfolder ./Orchids. All subfolders inside this level are exactly the same because each one corresponds to a reference sound. For example: CAMO_Iowa/Audio/AIS/ahh: Reference sound (ahh.wav) and 10 (ten) orchestrations (ahh_ais*.wav), where the wildcard * replaces a number between 1 and 10. (NOTE: the article only uses orchestrations 1-8. In some cases CAMO-AIS found fewer orchestrations. See article for details). CAMO_Iowa/Data/GA/ahh: Matlab structure (ahh_iowa_ga.mat) and text file (ahh_iowa_ga.txt) with the data relative to the orchestrations. Both .mat and .txt files have the same information. The .mat file requires Matlab to open, so the .txt file can be used whenever Matlab is not available. NOTE: The article (both objective measures and listening test) only includes 13 of the 26 reference sounds found here. The reference sounds used in the article are listed below: air_horn car_horn carnatic choir_tibetan didgeridoo factory_siren glass minimoog musical_saw purr scream_woman waterphone wind_harp NOTE: CAMO_SOL/Data/Orchids/* (any folder inside this level) only has the .mat file (no .txt file) because the application Orchids exports the results in different formats. The contents of the .mat file is similar (but not identical) to the other algorithms because Orchids does not export the same data. Finally, the contents of each file is described below with an example from CAMO_Iowa/Audio/AIS/ahh and CAMO_Iowa/Data/AIS/ahh. CAMO_Iowa/Audio/AIS/ahh/ahh.wav: reference sound CAMO_Iowa/Audio/AIS/ahh/ahh_iowa_ais1.wav: first orchestration returned (see text for meaning of ordering). Each orchestration consists of up to 5 (five) musical instrument sounds played in unison to approximate the reference sound perceptually. CAMO_Iowa/Data/AIS/ahh/ahh_iowa_ais.mat: Matlab data file containing the variables "reference", "additional", and "reference". Each variable is described in detail below. CAMO_Iowa/Data/AIS/ahh/ahh_iowa_ais.txt: Textual description of the information found in the corresponding .mat file Execute the command "load('ahh_iowa_ais.mat')" on the Matlab command window to load the variables to the workspace. (NOTE3: see article for meaning of information stored in variables). The structures are: orchestration: 1x10 structure array containing information about each orchestration. For example, orchestration(1) has data for the first orchestration (see the article for the meaning of the ordering of the orchestrations). reference: 1x1 structure containing information about the reference sound. additional: 1x1 structure containing the additional information in Appendix A of the article. "additional" has the following fields: additional.orch: Number of orchestrations found by CAMO-AIS additional.subspace: Size of the subspace additional.total: Total number of combinations "orchestration" has the following fields: orchestration.name: name of the corresponding orchestration orchestration.sounds: names of sounds used in the orchestration orchestration.fitness: fitness value of orchestration orchestration.distances: distances used in fitness calculation orchestration.estimated: values estimated with combination functions and features from individual sounds used in orchestrations orchestration.extracted: values extracted from audio of final mixture orchestration.estimated: orchestration.estimated.centroid: spectral centroid orchestration.estimated.spread: spectral spread orchestration.estimated.loudness: loudness value (dB RMS) orchestration.estimated.csp: contribution spectral peaks (CSP) of orchestration orchestration.estimated.csp.dBamp: amplitude of CSP in dB orchestration.extracted: orchestration.extracted.centroid: spectral centroid (Hz) orchestration.extracted.spread: spectral spread orchestration.extracted.loudness: loudness value (dB RMS) orchestration.extracted.f0: fundamental frequency (Hz) orchestration.extracted.rmsEnergy: root-mean-squared energy (dB) orchestration.extracted.totalEnergy: total energy orchestration.extracted.csp: contribution spectral peaks (CSP) of orchestration orchestration.extracted.csp.freq: frequency of CSP in Hz orchestration.extracted.csp.amp: amplitude of CSP orchestration.extracted.csp.dBamp: amplitude of CSP in dB "reference" has the following fields: reference.name: name of the reference sound reference.centroid: spectral centroid (Hz) reference.spread: spectral spread reference.loudness: loudness value (dB RMS) reference.f0: fundamental frequency (Hz) reference.rmsEnergy: root-mean-squared energy (dB) reference.totalEnergy: total energy reference.csp: contribution spectral peaks (CSP) of orchestration reference.csp.freq: frequency of CSP in Hz reference.csp.amp: amplitude of CSP reference.csp.dBamp: amplitude of CSP in dB
