About:
Speexdsp is an open-source audio processing library focused on voice processing. It provides essential functions like acoustic echo cancellation, noise suppression, and automatic gain control. This library is designed to improve voice quality in telephony and VoIP applications.
Key Features:
  • Acoustic Echo Cancellation (AEC)
  • Noise Suppression
  • Automatic Gain Control (AGC)
  • Voice Activity Detection (VAD)
Use Cases:
  • Improving audio quality in VoIP applications
  • Processing microphone input for voice recognition
  • Developing real-time communication software
Alternatives:
  • WebRTC Audio Processing – More modern and widely used in browsers, but Speexdsp is lighter and specifically tied to the Speex codec ecosystem.
  • RNNoise – Focuses primarily on noise suppression using deep learning, whereas Speexdsp offers a broader suite of traditional DSP algorithms.
