Multi-Pulse Excited Encoder for WAV Audio Files

The multi-pulse excited encoder combined with long-term prediction synthesis technology enables the creation of entirely new audio files. The multi-pulse excited encoder is an audio compression algorithm that encodes sound data into smaller file sizes while maintaining high-quality audio performance. This algorithm typically works by identifying significant excitation pulses in the audio signal and encoding their positions and amplitudes, often implemented using code that calculates optimal pulse locations through analysis-by-synthesis methods. Long-term prediction synthesis technology synthesizes extended audio files based on previous audio signals, commonly using pitch prediction and periodicity analysis to generate sustained sound segments. Through these advanced technologies, which may involve implementing LPC (Linear Predictive Coding) coefficients and adaptive codebook approaches, we can create more diverse and richer sound experiences. The process typically includes feature extraction, pattern matching, and signal reconstruction phases in the code implementation.
