  2. Sub-band coding - Wikipedia

    en.wikipedia.org/wiki/Sub-band_coding

    In signal processing, sub-band coding (SBC) is any form of transform coding that breaks a signal into a number of different frequency bands, typically by using a fast Fourier transform, and encodes each one independently. This decomposition is often the first step in data compression for audio and video signals.

  3. Time-domain harmonic scaling - Wikipedia

    en.wikipedia.org/wiki/Time-domain_harmonic_scaling

    Time-domain harmonic scaling (TDHS) is a method for time-scale modification of speech (or other audio signals), [1] allowing the apparent rate of speech articulation to be changed without affecting the pitch-contour and the time-evolution of the formant structure. [2]

  4. Adaptive differential pulse-code modulation - Wikipedia

    en.wikipedia.org/wiki/Adaptive_differential...

    G.722 [4] is an ITU-T standard wideband speech codec operating at 48, 56 and 64 kbit/s, based on subband coding with two channels and ADPCM coding of each. [5] Before the digitization process, it catches the analog signal and divides it in frequency bands with quadrature mirror filters (QMF) to get two subbands of the signal.

  5. Speech coding - Wikipedia

    en.wikipedia.org/wiki/Speech_coding

    Speech coding is an application of data compression to digital audio signals containing speech. Speech coding uses speech-specific parameter estimation using audio signal processing techniques to model the speech signal, combined with generic data compression algorithms to represent the resulting modeled parameters in a compact bitstream. [1]

    en.wikipedia.org/wiki/Category:Speech_codecs

    Speech codecs differ from Audio codecs in that they are optimized for speech signals. Human speech can be modeled easier than generic audio. This means that high quality speech can be coded with specific methods better than generic audio. On the other hand humans are very good at hearing problems with human speech signal.

  8. Temporal envelope and fine structure - Wikipedia

    en.wikipedia.org/wiki/Temporal_envelope_and_fine...

    The coding of temporal information in the auditory nerve can be disrupted by two main mechanisms: reduced synchrony and loss of synapses and/or auditory nerve fibers. [186] The impact of disrupted temporal coding on human auditory perception has been explored using physiologically inspired signal-processing tools.
