Job Summary:

Audio Signal Processing Engineer

Key Responsibilities:

• Design and implement audio signal processing algorithms, including filtering, noise reduction, echo cancellation, and beamforming.
  
• Apply

  Fourier Transform techniques

  (FFT, STFT, etc.) to analyze, visualize, and manipulate audio signals.
• Work with time-domain and frequency-domain audio features for applications such as speech enhancement, recognition, and classification.
  
• Collaborate with cross-functional teams (e.g., ML, embedded, frontend) to integrate DSP modules into products.
  
• Evaluate and optimize algorithm performance in terms of latency, accuracy, and computational efficiency.
  
• Perform audio data acquisition, preprocessing, and annotation tasks as required.
  
• Maintain clear documentation of processes, algorithms, and performance benchmarks.
  

Required Skills:

• Strong understanding of

  Audio Signal Processing

  concepts and algorithms.
• Proficient in

  Fourier Transformations

  (FFT, DFT, STFT) and spectral analysis.
• Hands-on experience with
