SFR-v1: FM Reception Speech Dataset
Dataset Summary
SFR-v1 consists of segmented 10-second FM reception audio clips accompanied by frame-level RSSI (Received Signal Strength Indicator) traces. This dataset is designed to support research in hybrid digital-analog communication, channel-aware audio recovery, speech enhancement, and FM channel modeling. It includes multiple content types (news, music, speech, male and female voices) under varying channel quality conditions.
Audio Parameters
- Sample rate: 24 kHz
- Bit depth: 16-bit PCM
- Channels: Mono
RSSI Parameters
- Acquisition: a probe signal used solely for RSSI acquisition and not part of the audio
- Original interval: ~60 ms per measurement (with timestamp)
- Resampling: interpolated to 50 ms per step, yielding 200 RSSI values per 10-second clip
- Raw range: approximately –65 dBm to –105 dBm
- Normalization: linearly mapped to [4, 20], where higher values indicate poorer channel quality
- Alignment: RSSI sequences are frame-aligned with each audio segment
