【盤の特長・超激レア!技術実証盤】
本作は、1991年にサー・コリン・デイヴィス指揮で行われた伝説的なライヴ録音ですが、その真の価値は、このCDが持つ特殊な出自にあります。
ブックレット(英語解説「Preface」)によると、このCDは、バイエルン放送 (BR) とミュンヘン放送技術研究所 (IRT) が、当時開発中だったデジタルオーディオ符号化技術「MUSICAM technique」の主観評価(音質差の検証)を目的として、1991年12月に特別に制作したものです。

【解説要約:MUSICAM技術とは】
MUSICAMは、後のDAB(デジタルラジオ)放送などで採用される音声圧縮技術の先駆けです。人間の聴覚特性(マスキング効果)を利用し、聴感上の音質を維持したまま、デジタル音声のデータ量をCDの約1/7(ステレオ少なくとも193 kbit/s)に劇的に削減することを可能にします。このCDには、このMUSICAM技術によって「様々なレベルのデータ削減」が適用された状態の音源が収録されており、その音質差を比較・研究するための非常に特殊な盤です。一般の音楽市場には流通しておらず、放送・音響技術関係者向けに配布された非売品である可能性が極めて高く、コレクターにとって垂涎の「超激レア」アイテムです。

【コンディション】
中古品として「やや傷や汚れあり」の状態です。
● ジャケット・ブックレット:経年による使用感、スレ、薄い汚れが見られます。
● 盤面:再生に支障のない程度の薄いスレ・小傷が見られる場合があります。
● ケース:スレ、小傷、汚れあり。

【詳細データ】
● カタログコード:BRTD 004
● JANコード:無し(特殊盤のため)
● 録音:1991年4月(ライヴ)

【For International Buyers】
ULTRA RARE! Brahms: Symphony No. 1. Sir Colin Davis / Symphonieorchester des Bayerischen Rundfunks (1991 Live).
Catalog No.: BRTD 004.
This is a special technical demonstration CD produced by Bavarian Broadcasting (BR) and the Institute for Broadcast Technology (IRT) for the subjective evaluation of the ""MUSICAM technique"" (a precursor to DAB audio coding). It contains tracks with ""various levels of data reduction"" applyed. Not commercially available, likely for broadcast/audio professionals only. Truly unique and ultra-rare collectible.
Condition: Good (Shows some signs of wear and aging).

MUSICAMという技術、あまりに気になったので、aiに調べてもらいました:
【超弩級・技術実証盤の正体:MUSICAM技術とは】
本盤は1991年当時、次世代デジタル放送(DAB)の標準規格を争っていた最先端圧縮技術「MUSICAM」の実証のために制作された非売品です。
MUSICAMは後のMP3のベースとなった技術ですが、本CDにはバイエルン放送の威信をかけ、デイヴィス指揮BRSOによるガスタイクでのライヴ音源が「データ削減による音質変化の検証用」として収められています。

人間の聴覚特性(マスキング効果)を利用したデジタル演算処理が、ガスタイクホールの広大な残響と化学反応を起こした結果、通常の市販盤では絶対に聴けない「異様なまでの空間の透明度と空気感」が定着しています。まさに音響工学と芸術が交差した、歴史的にも極めて貴重な1枚です。
