Examples of lossless audio content distribution formats includeįLAC. Lossless data compression algorithm that preserves bit accuracy across encoding and decoding, where the result of decoding previously encoded data is equivalent to the original data. Time delay as a signal passes through a system. Representation with greater bit-depth and sample rate than CDs (stereo 16-bit PCM at 44.1 kHz) and without lossy data compression. Synonym for high-resolution audio (but different than Intel High Definition Audio). Multiplicative factor greater than or equal to 1.0, applied to an audio signal to increase the signal level. The audio HAL interface uses the concept of frames per buffer. Number of frames handed from one module to the next at one time. Set of samples, one per channel, at a point in time. In an audio context, the data stored in the queue are typically audio frames.

Hardware module or software data structure that implementsįirst In, First Out queueing of data. For example, if music is playing when a notification arrives, the music ducks while the notification plays. Temporarily reduce the volume of a stream when another stream becomes active. Super Audio CD (SACD) and in DSD over PCM (DoP) for USB. DSD is better suited to content distribution than as an internal representation for processing as it can be difficult to apply traditional digital signal processing (DSP) algorithms to DSD. Both PCM and DSD represent multiple channels by independent sequences.

While Pulse Code Modulation (PCM) encodes a waveform as a sequence of individual audio samples of multiple bits, DSD encodes a waveform as a sequence of bits at a very high sample rate (without the concept of samples). Simple mixing without attenuation or limiting has the potential for overflow and clipping. Accomplished by dropping channels, mixing channels, or more advanced signal processing. Single stream of audio information, usually corresponding to one location of recording or playback.ĭecrease the number of channels, such as from stereo to mono or from 5.1 to stereo. Number of bits of information per sample. Person concerned with a superior music reproduction experience, especially willing to make substantial tradeoffs (expense, component size, room design, etc.) for sound quality. Multiplicative factor less than or equal to 1.0, applied to an audio signal to decrease the signal level. Study of the mechanical properties of sound, such as how the physical placement of transducers (speakers, microphones, etc.) on a device affects perceived audio quality. Digital Audioĭigital audio terms relate to handling sound using audio signals encoded in digital form. Generic audio-related terms have conventional meanings. This glossary of audio-related terminology includes widely-used generic terms and Android-specific terms.
