(sound source: 100 ms white noise from 90° azimuth, 0° elevation) The interaural time difference (or ITD) when concerning humans or animals, is the difference in arrival time of a sound between two ears. It is important in the localization of sounds, as it provides a cue to the direction or angle of the sound source from the head. If a signal ...
Latency refers to a short period of delay (usually measured in milliseconds) between when an audio signal enters a system, and when it emerges.Potential contributors to latency in an audio system include analog-to-digital conversion, buffering, digital signal processing, transmission time, digital-to-analog conversion, and the speed of sound in the transmission medium.
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 ...
ASIO 2.3 introduced monitoring for dropouts in the audio stream. [4] ASIO bypasses the normal audio path from a user application through layers of intermediary operating system software so that an application connects directly to the sound card hardware. Each layer that is bypassed means a reduction in latency (the delay between an application ...
To their credit, though, Devantier tells me Samsung has done a lot of work on this problem over the past few years, and 2020 models now have the ability to adjust its delay in both directions ...
If the delay is fairly significant (more than a few hundred milliseconds), it is considered annoying. If the delay is very small (tens of milliseconds or less [3]), the phenomenon is called sidetone. If the delay is slightly longer, around 50 milliseconds, humans cannot hear the echo as a distinct sound, but instead hear a chorus effect. [3]

If a sound source and two microphones are arranged in a straight line, with the sound source at one end, then the following can be measured: The distance between the microphones (x), called microphone basis. The time of arrival between the signals (delay) reaching the different microphones (t). Then v = x/t.
