/three_band_filter_bank

extracted from webrtc, resample the 48k data to 16k while preserving the high band infomation, which can be used to synthesize back to the 48k data

Primary LanguageC++

three_band_filter_bank

  • extracted from the source code of webrtc
  • split the target 48k signal into three bands time domain data, which frequencies are ranging in 08kHz, 816kHz, 16~ 24kHz respectively, as well as synthesizing the three band data back to the original 48k signal (not perfect reconstruction)
