Speech Input, 8-bit PCM Audio Truncation, and Filtered Output

This project utilizes the MATLAB programming language to implement speech input functionality, performs truncation operations on 8-bit PCM audio, and generates output results through filtering. The primary application scenario involves truncating PCM audio with higher bit depths (greater than 8 bits) to convert it into 8-bit PCM format. This process typically involves reading audio data using functions like audioread(), followed by bit-depth reduction through quantization algorithms. The implementation may include scaling the audio signal to the appropriate range and applying rounding or truncation methods to achieve 8-bit precision. Filtering operations, potentially using digital filters like FIR or IIR designs, help maintain audio quality during the conversion process. Through this approach, we achieve enhanced compatibility and improved performance in speech processing applications, making the audio suitable for systems with 8-bit PCM requirements while minimizing quality degradation through proper signal conditioning.
