3. Bicycle built for two / arr. by M.V. Mathews [Daisy Bellのやつ](https://www.historyofinformation.com/detail.php?entryid=4445)。これバックグラウンドは三角波にエンベロープだけだから元のMUSICの可能性はあるのかな。他はヴォコーダーを別に使って録音なのかしら

1) A demonstration of ultrasonic detection and translation for industrial purposes. The container noted John Jarvis at RCA, who may be the narrator of this portion of the recording. 2) Demonstrations of computer speech, vocoding, vari-speed speech processing, harmonic processing, the artificial larynx (tone generator), and the Bell Telephone labs computer voice synthesizer.
|
||||||
|
|
||||||
|
前半:
|
||||||
|
|
||||||
|
Ultrasonic Translator 超音波を可聴域に引き伸ばしたもの
|
||||||
|
Bat sound???
|
||||||
|
マッチの炎から出てる超音波?
|
||||||
|
sinders?
|
||||||
|
|
||||||
|
electric type letter
|
||||||
|
|
||||||
|
トランジスタを落とす時の音を超音波ベースで解析して不良品を弾く、みたいなことを言っているな
|
||||||
|
|
||||||
|
後半:
|
||||||
|
|
||||||
|
Demo of Computer Speech、Vocoder, Harmonic Compression
|
||||||
|
|
||||||
|
Computer Speech DAC経由で/to be, or not to be
|
||||||
|
|
||||||
|
Vocoderはアナライズ、コーデック的なものの方を指すらしい
|
||||||
|
よくできてるなあーーー
|
||||||
|
|
||||||
|
ピッチを変えずにスピード上げる/落とす(Harmonic Compressor/Expander)ってそういうことか
|
||||||
|
|
||||||
|
Speed
|
||||||
|
|
||||||
|
Artificial Larinx トランジスタで作っていることが新規 当時でもUSに3000人声帯をなくした人がいる
|
||||||
|
流石にピッチはほとんど変えてない
|
||||||

最後に Daisy Bellのが

Scope/Content Note:
|
||||||
|
Max Mathews, performer.
|
||||||
|
|
||||||
|
1. Mar-ra-la-a -- Joseph Olive 声の引き伸ばしと、コンピューター合成の声と2つが同時に使われている 歌詞が説明になっていて、デモがそのまま曲になってるみたいな曲だ これどこまでがコンピューター合成なんだろう
|
||||||
|
2. String Quartet in F major (Third movement) -- Maurice Rave トレモロとかも含めて表現されてるのおもろ(結構チップチューンみたいな曲になってる) これ微妙にフィルターもエンベロープでいじってるか?
|
||||||
|
|
||||||
|
ていうかこれ全然ノイズなくて綺麗だな.この二つはレコード経由せずに直接デジタル化されたのかな
