The MPEG-7 Audio standard contains description tools for audio describing content. The extraction of low level descriptors is normative and is based on the audio signal itself. With the help of low level descriptors it is possible to search and filter audio content in regard to for e.g. spectrum, harmony, timbre and melody. 2. Low Level Tools

I just did some research on existing implementations of the MPEG-7 audio descriptors and found the following implementations: The official implementation of the 17 low-level descriptors ( part 1 and part 2) (MATLAB). Alghough the descriptors are implemented in MATLAB, it should not be a big issue to implement them in Python, based on the MATLAB code.

The consortium for low-level audio descriptorsIn the MPEG-7 standardisation process, the definition of audio descriptors is thus mandatory. To this end, a working group was charged with defining a reduced set of obvious descriptors. It is the so-called “audio consortium for low-level audio descriptors”.

segmentation is performed on MPEG-7 low level audio feature descriptors as a growing source of multimedia meta data. Especially for database applications or audio-on-demand services this technique could be very helpful, because there is no need to have access to the probably copyright protected original audio material. The result
