Adaptive differential pulse-code modulation (ADPCM) is a variant of differential pulse-code modulation (DPCM) that varies the size of the quantization step, to allow further reduction of the required data …

ADPCM stands for Adaptive Delta Pulse Code Modulation. In ADPCM, a difference value is stored, but this value has been mathematically adjusted based on the slope of the input waveform.

Jan 7, 2021 · Adaptive Differential Pulse Code Modulation (ADPCM) is a lossy compression format that is implemented for XAudio2 to provide additional features for specifying the size of the compression …

The term ADPCM stands for Adaptive Delta Pulse Code Modulation. In this modulation, a disparity value can be regulated mathematically based on the input waveform’s slope is stored.

Instead of encoding the speech sample, ADPCM encodes the difference between a predicted sample and the speech sample. This method provides more efficient compression with a reduction in the …

Jun 17, 2025 · ADPCM, or Adaptive Differential Pulse Code Modulation, is a widely used audio compression technique that has been employed in various applications, from telecommunications to …

Nov 10, 2025 · ADPCM, which stands for Adaptive Differential Pulse Code Modulation, is a form of digital audio compression that is used to reduce the amount of data required to represent audio signals.

The acronym refers to waveform codecs which instead of quantizing the sound signal directly, like linear PCM codecs, quantize the difference between the sound signal and a prediction that has been made …

Mar 17, 2025 · ADPCM is a type of DPCM (Differential Pulse Code Modulation). It is also a differential coding technique that uses differential values like DPCM. ADPCM was developed to overcome the …

PCM uses a lot of bits per second. This is mostly because audio has a large dynamic range, and is weighted towards lower frequencies.
