Mirex 2014: Optimizing the Fluctuation Pattern Extraction Process
نویسندگان
چکیده
Similar to the submissions of the previous years our submissions are based on the so-called block-level features (BLF). The main change in our 2014 submission was the modification of the feature extraction steps for the Logarithmic Fluctuation Pattern. Beside this modification the structure of all three algorithms did not changed. This abstract gives an overview on the feature set and presents some specific details of the submitted algorithms.

Extended Abstract for Audio Melody Extraction in Mirex 2010 (to Be Modified)
This extended abstract is for the “Audio Melody Extraction” evaluation in MIREX2010. We describe an algorithm that estimates the melody line from a music audio signal. The algorithm is comprised of two stages: melodic component enhancement and melody line tracking. Only a few researchers used this approach because of difficulties of the melody enhancement. Our enhancement algorithm focuses on t...
متن کاملMirex2014: Audio Melody Extraction
This paper describes our submission for the audio melody extraction task of the Music Information Retrieval Evaluation eXchange (MIREX 2014). Our algorithm first separates the vocal spectra from polyphonic sound spectra. Melody extraction and vocal activity detection are applied to the separated spectra.
متن کاملMirex 2005: Combined Fluctuation Features for Music Genre Classification
We submitted a system that uses combinations of three feature sets (Rhythm Patterns, Statistical Spectrum Descriptor and Rhythm Histogram) to the MIREX 2005 audio genre classification task. All feature sets are based on fluctuation of modulation amplitudes in psychoacoustically transformed spectrum data. For classification we applied Support Vector Machines. Our best approach achieved 75.27 % c...

متن کاملText Information Retrieval Approach to Music Information Retrieval
This MIREX submission for symbolic music similarity task adopts textual information retrieval methodology in the process of music information retrieval. The main contribution of this approach is to utilize well established term weighting methods for text retrieval and check their suitability for music data. We use a simple feature extraction method, so that the performance of an algorithm depen...
