melp_encode
- this code for audio compressing with mixed excitation linear prediction with rate 2400 bit per second and can use in many application in send and receive audio. better and advanced version of this program developed and is in use
melp_ana
- A block diagram of the MELP model of speech production is shown in Figure 17.1, which is an attempt to improve upon the existent LPC model.
stream-player
- Stream Audio Player delphi source code
melp_init
- The MELP coder depends on the computation of Fourier magnitudes the prediction-error signal to capture the shape of the excitation pulse, which basically are the magnitudes of the Fourier transform. These quantities are quantized and transmitte
melp_bandpass
- In this section, the procedure for Fourier magnitude computations is described examples using real speech signals are included to illustrate the technique. Note that Fourier magnitudes are calculated only when the frame is voiced or jittery voi
coeff
- During encoding, the magnitude of the DFT for the prediction error is found peaks of the magnitude spectrum corresponding to the harmonics associated with the pitch frequency are measured. The peak values are the Fourier magnitudes and are tra
FPR
- The procedure used by the FS MELP coder for Fourier magnitude calculations and quantizations is presented next (Figure 17.3). Inputs to the procedure are the speech data (200 samples), the LPC, and the pitch period. It is assumed that the LPC and
IQparse
- 经过无线电接收机所采集的IQ 数据经过本程序的解析，可得到音频数据。-Through radio receiver IQ data collected through the program parsing, audio data can be obtained.
