Product Highlights
8-Element Linear MEMS Microphone Array
GYHA-LA08-Pro integrates eight high-performance MEMS microphones arranged in a precise linear array structure. Compared with conventional single microphones or low-channel microphone arrays, the increased microphone density provides higher spatial sampling resolution, improved sound field reconstruction capability, and enhanced sound source localization accuracy.
Pure Raw Audio Output for Algorithm Development
Unlike commercial voice modules with embedded DSP processing, AMM-LA08-Pro outputs original, unprocessed microphone signals directly from the hardware.
The module does not apply:
- Noise suppression (NS)
- Acoustic echo cancellation (AEC)
- Automatic gain control (AGC)
- Voice enhancement algorithms
- Compression processing
This ensures the original acoustic characteristics are fully preserved, making it ideal for:
- AI speech dataset collection
- Acoustic algorithm research
- Beamforming algorithm development
- Sound localization experiments
- Professional audio analysis
High Precision Spatial Audio Capture
The eight microphones are synchronously sampled with accurate phase consistency, enabling precise spatial acoustic information acquisition.
The linear microphone arrangement provides strong directional characteristics and creates a solid hardware foundation for:
- Direction of arrival (DOA) estimation
- Beamforming
- Sound source tracking
- Spatial audio analysis
Long-Distance Far-Field Pickup Capability
Through optimized acoustic design and high-performance audio acquisition circuitry, GYHA-LA08-Pro supports effective far-field voice capture up to 10 meters.
The module can accurately capture:
- Human speech
- Environmental sounds
- Weak acoustic signals
- Multi-source audio scenes
while maintaining excellent signal integrity.
Plug-and-Play USB Integration
The module adopts a standard USB audio interface, supporting:
- Windows
- Linux
- Android
- Embedded platforms
No additional driver development is required, allowing rapid integration into:
- Smart conferencing terminals
- AI voice devices
