The Subjective Importance of Uniform Group Delay at Low Frequencies

Document Thumbnail

Analog recordings always have high group delay at low frequencies due to the combined effects of all the components in the record/replay chain, and in particular the analog recorder. Digital recorders now make it practical to remove much of this group delay. It is discussed whether it is worthwhile to produce a record/replay chain having uniform group delay down to the lowest audible frequencies.
