  2. Pitch correction - Wikipedia

    en.wikipedia.org/wiki/Pitch_correction

    Pitch correction devices do this without affecting other aspects of its sound. Pitch correction first detects the pitch of an audio signal (using a live pitch detection algorithm), then calculates the desired change and modifies the audio signal accordingly. The widest use of pitch corrector devices is in Western popular music on vocal lines.

  3. Pitch shifting - Wikipedia

    en.wikipedia.org/wiki/Pitch_shifting

    Older digital processors could often shift pitch only in post-production, whereas many modern devices using computer processing technology can change pitch values virtually in real time. [ 4 ] Pitch correction is a form of pitch shifting and is found in software such as Auto-Tune and Melodyne to correct intonation inaccuracies in a recording or ...

  6. Audio time stretching and pitch scaling - Wikipedia

    en.wikipedia.org/wiki/Audio_time_stretching_and...

    The simplest way to change the duration or pitch of an audio recording is to change the playback speed. For a digital audio recording, this can be accomplished through sample rate conversion. When using this method, the frequencies in the recording are always scaled at the same ratio as the speed, transposing its perceived pitch up or down in ...

  7. Audio Random Access - Wikipedia

    en.wikipedia.org/wiki/Audio_Random_Access

    ARA increases the amount of communication possible between DAW software and a plug-in, allowing them to exchange important information, such as audio data, tempo, pitch, and rhythm, for an entire song, rather than just at the moment of playback.

  8. Phase vocoder - Wikipedia

    en.wikipedia.org/wiki/Phase_vocoder

    The computer algorithm allows frequency-domain modifications to a digital sound file (typically time expansion/compression and pitch shifting). At the heart of the phase vocoder is the short-time Fourier transform (STFT), typically coded using fast Fourier transforms.

  9. Effects unit - Wikipedia

    en.wikipedia.org/wiki/Effects_unit

    A harmonizer is a type of sophisticated pitch shifter that combines the altered pitch with the original pitch to create a two note harmony based on the original pitch, or even with some pedals, three note harmony. Some hamonizers are able to create chorus-like effects by adding very tiny shifts in pitch.
