Group Delay in Audio
Group delay has some importance in the audio field and especially in the sound reproduction field. Many components of an audio reproduction chain, notably loudspeakers and multiway loudspeaker crossover networks, introduce group delay in the audio signal. It is therefore important to know the threshold of audibility of group delay with respect to frequency, especially if the audio chain is supposed to provide high fidelity reproduction. The best thresholds of audibility table has been provided by Blauert & Laws (1978).
| Frequency | Threshold |
|---|---|
| 500 Hz | 3.2 ms |
| 1 kHz | 2 ms |
| 2 kHz | 1 ms |
| 4 kHz | 1.5 ms |
| 8 kHz | 2 ms |

Famous quotes containing the words group and/or delay:
“We often overestimate the influence of a peer group on our teenager. While the peer group is most influential in matters of taste and preference, we parents are most influential in more abiding matters of standards, beliefs, and values.”
—David Elkind (20th century)
“Face troubles from their birth, for ‘tis too late to cure
When long delay has given the evil strength.
Haste then; postpone not to the coming hour: tomorrow
He’ll be less ready who’s not ready now.”
—Ovid (Publius Ovidius Naso)
