  2. WAV - Wikipedia

    en.wikipedia.org/wiki/WAV

    Waveform Audio File Format (WAVE, or WAV due to its filename extension; [3] [6] [7] pronounced / w æ v / or / w eɪ v / [8]) is an audio file format standard for storing an audio bitstream on personal computers. The format was developed and published for the first time in 1991 by IBM and Microsoft.

  3. Spectrogram - Wikipedia

    en.wikipedia.org/wiki/Spectrogram

    In deep learning-keyed speech synthesis, spectrogram (or spectrogram in mel scale) is first predicted by a seq2seq model, then the spectrogram is fed to a neural vocoder to derive the synthesized raw waveform. By reversing the process of producing a spectrogram, it is possible to create a signal whose spectrogram is an arbitrary image.

  4. Waveform - Wikipedia

    en.wikipedia.org/wiki/Waveform

    A sine, square, and sawtooth wave at 440 Hz A composite waveform that is shaped like a teardrop. A waveform generated by a synthesizer. In electronics, acoustics, and related fields, the waveform of a signal is the shape of its graph as a function of time, independent of its time and magnitude scales and of any displacement in time.

  5. Ringing artifacts - Wikipedia

    en.wikipedia.org/wiki/Ringing_artifacts

    The main cause of ringing artifacts is overshoot and oscillations in the step response of a filter.. The main cause of ringing artifacts is due to a signal being bandlimited (specifically, not having high frequencies) or passed through a low-pass filter; this is the frequency domain description.

  6. Optical sound - Wikipedia

    en.wikipedia.org/wiki/Optical_sound

    The width of the white area is proportional to the amplitude of the audio signal at each instant. Most of the inventions which led to optical sound-on-film technology employed the use of an electric lamp, called an 'exciter', shining through a translucent waveform printed on the edge of a film strip. When the light shines through the film, it ...

  7. Sampling (signal processing) - Wikipedia

    en.wikipedia.org/wiki/Sampling_(signal_processing)

    When it is necessary to capture audio covering the entire 20–20,000 Hz range of human hearing [6] such as when recording music or many types of acoustic events, audio waveforms are typically sampled at 44.1 kHz , 48 kHz, 88.2 kHz, or 96 kHz. [7] The approximately double-rate requirement is a consequence of the Nyquist theorem. Sampling rates ...

  8. Amplitude modulation - Wikipedia

    en.wikipedia.org/wiki/Amplitude_modulation

    In electronics, telecommunications and mechanics, modulation means varying some aspect of a continuous wave carrier signal with an information-bearing modulation waveform, such as an audio signal which represents sound, or a video signal which represents images. In this sense, the carrier wave, which has a much higher frequency than the message ...

  9. Audio search engine - Wikipedia

    Keywords are generated from the analysed image. These keywords are used to search for audio files in the database. The results of the search are displayed according to the user preferences regarding to the type of file (wav, mp3, aiff…) or other characteristics.
