Table 3 Source separation results for 5 s of MP3-coded speech

From: Perceptually controlled doping for audio source separation

No. of sources SDR (dB) SDR sparse (dB) SIR (dB) SIR sparse (dB) SAR (dB) SAR sparse (dB)
2 30.3 33.3 53.0 55.8 30.4 33.3
3 13.2 14.8 20.4 22.0 14.4 16.0
4 9.0 10.4 15.2 16.5 10.5 12.1
5 5.8 7.3 11.2 12.7 7.8 9.5
6 3.3 4.8 8.1 9.4 6.1 7.6
  1. SDR, SIR, and SAR (in dB) for original and sparsified signals. Mean values of 100 simulations with 5-s speech signals after MP3 coding/decoding process.
