Neural Audio Fingerprint Dataset

(c) 2021 by Sungkyun Chang https://github.com/mimbres/neural-audio-fp

This dataset includes all music sources, background noise and impulse-reponses (IR) samples that have been used in the work ["Neural Audio Fingerprint for High-specific Audio Retrieval based on Contrastive Learning"] (https://arxiv.org/abs/2010.11910).

Format:

16-bit PCM Mono WAV, Sampling rate 8000 Hz

Data source:

• Bacgkound noise from Audioset was retrieved using key words ['subway', 'metro', 'underground', 'not music'] • Cochlear.ai pub-noise was recorded at the Strabucks branches in Seoul by Jeongsoo Park. • Random noise was generated by Donmoon Lee. • Room/space IR data was collected from Aachen IR and OpenAIR 1.4 dataset. • Portions of MIC IRs were from Vintage MIC (http://recordinghacks.com/), and pre-processed with room/space IR data. • Portions of MIC IRs were recorded by Donmoon Lee, Jeonsu Park and Hyungui Lim using mobile devices in the anechoic chamber at Seoul National University. • All music sources were taken from the Free Music Archive (FMA) data set, and converted from stereo 44Khz to mono 8Khz. • train-10k-30s contains all 8K songs from FMA_small. The remaining 2K songs were from FMA_medium. • val- and test- data were isolated from train-, and taken from FMA_medium. • test-query-db-500-30s/query consists of the pre-synthesized 2,000 queries of 10s each (SNR 0~10dB) and their corresponding 500 songs of 30s each. • Additionally, query_fixed_SNR directory contains synthesized queries with fixed SNR of 0dB and -3dB. • dummy-db-100k was taken from FMA_full, and duplicates with other sets were removed.
