Research direction

No files, tests, or entry points are named. Start by turning the issue's requirements into a comparison of HDF5, Arrow, and Parquet: floating-point arrays, feature metadata, sampling rate, multiple representations per file, and broad language support. Done means a format and implementation direction are agreed.

Description

enhancement

We currently target annotation of audio and video files, but sometimes it might be not possible to keep the raw media. In that case it would be great to support other representations, e.g. spectrograms.

To add such support we have to decide on a binary format that is able to store floating point arrays and meta information like feature name and sampling rate, and comes with libraries for all common programming languages. HDF5 might be a good candidate, but we should also have a look at new formats like arrow or parquet, which might provide faster access. It should also be possible to store several feature representations in the same file as audformat supports only a single file column.
