Howling Corrupted Music and Speech dataset (HCMS)

The database contains in total 28 music files and 30 speech files. Each file is a 20 s excerpt where the howling is simulated to start between the 8th and 9th second. This is simulated by feeding the music or speech source signal to a closed-loop system with a varying broadband gain. A total of 8 acoustic impulse responses (AIRs) were used for the simulations, hence covering a wide range of howling frequencies. The final dataset1 contains fewer excerpts than the number of excerpts originally generated, as it went through a pruning step conducted by three experts, aiming to eliminate unsuitable examples (exhibiting howling at multiple howling frequencies or no howling at all).
