  2. Mel scale - Wikipedia

    en.wikipedia.org/wiki/Mel_scale

    The reference point between this scale and normal frequency measurement is defined by assigning a perceptual pitch of 1000 mels to a 1000 Hz tone, 40 dB above the listener's threshold. Above about 500 Hz, increasingly large intervals are judged by listeners to produce equal pitch increments.

  3. Piano key frequencies - Wikipedia

    en.wikipedia.org/wiki/Piano_key_frequencies

    The frequency of a pitch is derived by multiplying (ascending) or dividing (descending) the frequency of the previous pitch by the twelfth root of two (approximately 1.059463). [1] [2] For example, to get the frequency one semitone up from A 4 (A ♯ 4), multiply 440 Hz by the twelfth root of two.

  4. Scientific pitch - Wikipedia

    en.wikipedia.org/wiki/Scientific_pitch

    Scientific pitch, also known as philosophical pitch, Sauveur pitch or Verdi tuning, is an absolute concert pitch standard which is based on middle C (C 4) being set to 256 Hz rather than approximately 261.63 Hz, [1] making it approximately 31.77 cents lower than the common A440 pitch standard.

  5. A440 (pitch standard) - Wikipedia

    en.wikipedia.org/wiki/A440_(pitch_standard)

    A440 (also known as Stuttgart pitch [1]) is the musical pitch corresponding to an audio frequency of 440 Hz, which serves as a tuning standard for the musical note of A above middle C, or A 4 in scientific pitch notation. It is standardized by the International Organization for Standardization as ISO 16.

  7. Pitch detection algorithm - Wikipedia

    en.wikipedia.org/wiki/Pitch_detection_algorithm

    The fundamental frequency of speech can vary from 40 Hz for low-pitched voices to 600 Hz for high-pitched voices. [12] Autocorrelation methods need at least two pitch periods to detect pitch. This means that in order to detect a fundamental frequency of 40 Hz, at least 50 milliseconds (ms) of the speech signal must be analyzed.

  8. Voltage-controlled oscillator - Wikipedia

    en.wikipedia.org/wiki/Voltage-controlled_oscillator

    VCOs are used in synthesizers to generate a waveform whose pitch can be adjusted by a voltage determined by a musical keyboard or other input. A voltage-to-frequency converter (VFC) is a special type of VCO designed to be very linear in frequency control over a wide range of input control voltages. [1] [2] [3]

  9. 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 .
