Combination of two signals with different sample rates
13 ビュー (過去 30 日間)
I want to combine two signals with different sampling rate. I have have 2 sound signals, one (A) has telephone quality (Fs = 8Kz) and the other (B) music CD quality(Fs = 44.1 KHz). I want to add the music from file B to file A as a music investment (need someweakening). The duration of the result is equal to the longer of A and B.
How i can manage it??

Use a timetable, and call synchronize. synchronize uses interp1, but it may be that you particularly want to use the SP-oriented resample function instead:
ttHighFreq.yUpsampled = resample(ttLowFreq.y,...)
