title: BlueData: A Dataset of Perceptual Audio Degradations Caused by Wireless Packet Loss

description: BlueData is a dataset of clean and degraded music segments recorded under controlled wireless Bluetooth transmission conditions. Audio degradation results from real packet loss induced by signal attenuation.

The dataset consists of 2-second audio clips, each labeled as:

0 → Clean (no audible degradation)1 → Degraded (perceptual artifacts caused by Bluetooth packet loss)

All labels were assigned through human auditory inspection by certified QA testers.This dataset supports research on:





Perceptual sound event detection




Anomaly detection in audio




Wireless audio quality assessment in black-box testing environments



 

Annotation Process

Each audio segment was labeled through a two-pass auditory inspection process. Initially, one QA tester with ISTQB CTFL certification listened to each segment and labeled it as either clean or degraded.  A second certified tester independently reviewed all labels. In cases of disagreement, the final label was determined through discussion and consensus. This process ensured perceptual validity and consistency across the dataset.

Label encoding:0 = Clean (no audible degradation)1 = Degraded (perceptual artifact present due to Bluetooth packet loss)

 

Dataset Coverage & Structure

Training Set:





train/0/ → 11,760 clean audio segments




train/1/ → 3,757 degraded audio segments



Test Set:





test/ → 3,880 mixed segments



 

Original Audio Properties





Source: Free Music Archive (FMA)




Format: WAV, mono, 44.1 kHz




Segment duration: 2 seconds




Bitrate: Varies (typically 192–320 kbps MP3 before conversion)



Tracks were selected from a variety of musical genres and converted to WAV format under uniform preprocessing conditions.This variation reflects the diversity found in real-world streaming content.

 

Notes





No other types of distortion (e.g., clipping, filtering, compression) were introduced. Only real artifacts from Bluetooth transmission loss.




The genre distribution was not balanced or controlled, as this dataset is intended for perceptual degradation detection rather than genre classification.
