Things I learned on Phono EQ curves, Pt. 5


This article is a sequel to “Things I learned on Phono EQ curves, Pt.0”, “Pt.1”, “Pt.2”, “Pt.3” and “Pt.4”.

前回 は、トーキー映画用のディスク録音、民生用長時間レコード、放送局用トランスクリプション盤、ベル研/WEの縦振動トランスクリプション盤など、あれこれについて調べました。

On the previous part, I studied on the history of the “sound-on-disc” soundtracks for talking motion pictures, “Program Transcription” long playing record for consumer, Electrical Transcription discs for radio industry, Bell/WE’s vertical transcription technology, etc.


This time, I am going to continue learning the history, including the lateral transcription records, as well as the first standardization of recording/reproducing curve.

Mr. Frederick and Mr. Stokowski (1932)
