This is the preparation data needed to make musdb-L and musdb-XL data. Musdb-L and musdb-XL are the variants of musdb18-HQ dataset. We built musdb-L and XL by applying the iZotope Ozone 9 Maximizer (which is a widely used commercial digital limiter) to the original musdb18-HQ dataset. We included all parameter settings that were used in making musdb-L and XL. Note that the data in this page is not an audio waveform itself, this is just a sample-wise (element-wise) metadata of gain ratio between original musdb-hq vs musdb-L or XL. Check our github repository (https://github.com/jeonchangbin49/musdb-XL) or paper (https://arxiv.org/abs/2208.14355) for the detailed explanation.
