About the restored edition

These listening copies use gentle reduction of low rumble and background noise, with a fixed listening-level adjustment for each recording. The complete decoded duration and the original mono format are retained. Original HQ recordings remain available beside every player.

The original recordings are historical archive sources. Restored v2 is a separate listening edition.

Audio Letter 78 · Part 02: this unusually quiet recording also uses brief peak limiting to bring its listening level closer to the rest of the collection. The individual adjustment is recorded with its restoration profile; the complete recording and pauses are retained.
