| | # MSRBench: A Benchmarking Dataset for Music Source Restoration |
| |
|
| | MSRBench is the validation dataset for the MSR Challenge 2025 (https://msrchallenge.com); it contains 250 professionally mixed audio clips and their corresponding ground-truth targets under both original mix and 12 degradation scenarios in three categories. |
| |
|
| |
|
| | ## Download |
| | `hf download yongyizang/MSRBench --repo-type dataset --local-dir {your output dir}` |
| |
|
| | Total file size after unzipping is 28.7 GB. |
| |

| | ## Degradation Types |
| | |
| | #### DT0: Original mixture produced by mixing engineers. |
| | |
| | ### DT1-4: Analog and Environmental Distortions |
| | #### Radio (DT1) |
| | Simulates FM broadcasting using GNU Radio's stereo multiplex encoding/decoding blocks with standard broadcast parameters: |
| | |
| | **Signal Processing Parameters:** |
| | - Audio sampling rate: 44.1 kHz |
| | - Quadrature rate: 220.5 kHz |
| | - Pre-emphasis/de-emphasis time constant: 75 μs (US standard) |
| | - Maximum frequency deviation: 75 kHz |
| | - Stereo pilot tone: 19 kHz |
| | |
| | **Channel Model:** |
| | - **Rayleigh fading:** 8-sinusoid sum-of-sinusoids model with 20 Hz maximum Doppler shift |
| | - **Carrier frequency offset:** σ = 0.1, max 1 kHz variations |
| | - **Multipath channel:** 3-tap configuration |
| | - Delays: [0, 0.1, 0.5] ms |
| | - Relative magnitudes: [1.0, 0.8, 0.3] |
| | - **Noise:** Additive white Gaussian noise at approximately 26 dB SNR (noise amplitude = 0.05) |
| | |
| | #### Cassette (DT2) |
| | Models magnetic tape coloration and noise using the DAW Cassette plugin by Klevgrand.[^1] |
| | |
| | #### Vinyl (DT3) |
| | Reproduces playback artifacts including crackle and mechanical noise using iZotope Vinyl,[^2] configured with the "1970" preset. |
| | |
| | #### Live Sound (DT4) |
| | Generated using: |
| | - Impulse responses from PyRoomAcoustics |
| | - Bandpass filtering to approximate phone microphone characteristics |
| | - Environmental noise from the WHAM! dataset 48 kHz version mixed at approximately 20 dB SNR |
| | |
| | ### DT5-8: Traditional Lossy Audio Codecs |
| | |
| | #### DT5: 64 Kbps AAC |
| | |
| | #### DT6: 64 Kbps MP3 |
| | |
| | #### DT7: 128 Kbps AAC |
| | |
| | #### DT8: 128 Kbps MP3 |
| | |
| | ### DT9-12: Neural Audio Codecs |
| | |
| | #### DT9: 22 kHz Descript Audio Codec (DAC) |
| | |
| | #### DT10: 44 kHz DAC |
| | |
| | #### DT11: 6 Kbps Encodec |
| | |
| | #### DT12: 3 Kbps Encodec |
