2. Head-related transfer function - Wikipedia

   en.wikipedia.org/wiki/Head-related_transfer_function

   HRTF filtering effect. A head-related transfer function (HRTF) is a response that characterizes how an ear receives a sound from a point in space. As sound strikes the listener, the size and shape of the head, ears, ear canal, density of the head, size and shape of nasal and oral cavities, all transform the sound and affect how it is perceived, boosting some frequencies and attenuating others.

3. Latency (audio) - Wikipedia

   en.wikipedia.org/wiki/Latency_(audio)

   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.

4. LDAC (codec) - Wikipedia

   en.wikipedia.org/wiki/LDAC_(codec)

   LDAC is an alternative to Bluetooth SIG's SBC codec. Its main competitors are Huawei's L2HC, Qualcomm's aptX-HD/aptX Adaptive and the HWA Union/Savitech's LHDC. [1]LDAC utilizes a type of lossy compression [2] [3] by employing a hybrid coding scheme based on the modified discrete cosine transform [4] and Huffman coding [5] to provide more efficient data compression.

5. Delayed auditory feedback - Wikipedia

   en.wikipedia.org/wiki/Delayed_Auditory_Feedback

   Delayed Auditory Feedback (DAF), also called delayed sidetone, is a type of altered auditory feedback that consists of extending the time between speech and auditory perception. [1] It can consist of a device that enables a user to speak into a microphone and then hear their voice in headphones a fraction of a second later.

6. Delay (audio effect) - Wikipedia

   en.wikipedia.org/wiki/Delay_(audio_effect)

   Delay is an audio signal processing technique that records an input signal to a storage medium and then plays it back after a period of time. When the delayed playback is mixed with the live audio, it creates an echo-like effect, whereby the original audio is heard followed by the delayed audio. The delayed signal may be played back multiple ...

8. Echo suppression and cancellation - Wikipedia

   en.wikipedia.org/wiki/Echo_suppression_and...

   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]
