Measuring music transcription results based on a hybrid decay/sustain evaluation

2009

Although much work is being done in music transcription research, the evaluation of these techniques is less addressed by the research community. The lack of widely accepted metrics and databases presents an obstacle to the assessment of existing music transcription approaches. This paper presents an analysis of existing metrics and proposes a new method for measuring the results of music transcription. Based on the idea that decay and sustained music instruments may have different requirements, a dual process is implemented. On the decay process, a note oriented approach is used, considering pitches and onsets, generating a score for each note. On the sustain process, a time oriented appro…
