[music-dsp] Blend two audio

Hi, I'm looking for an algorithm to blend two audio. My requirement is given tow identical audio inputs say A1 & A2. A1 is ahead of A2 by t sec, when switch from A1 to A2 it should be seamless and vice versa. -ben ___ dupswapdrop: music-dsp mailing

Hi GM, >> HT -> Atan2 -> differenciate -> unwrap Could you please explain how to find the drift using HT, HT -> gives real(I) & imaginary (Q) components of real signal Atan2 -> the phase of an I Q signal diff-> gives what ? unwrap ? -ben From:

[music-dsp] Clock drift and compensation

Hi All, I have a problem to solve, I have a system which has a tuner chip and DSP chip, both are clocked by independent xtals. Tuner gives the baseband samples to DSP, and tuner is master and dsp is slave. Dsp does the demodulation of base band samples and does the audio decoding and

Hi, I want to develop an algorithm which after capturing an analog sine tone through PC sound card check for discontinuity, glitch, audio gap, attenuation etc. Please suggest any other reliable methods for this analysis. The sine tone is of fixed frequency which is known prior -ben
