Mr. U, formerly of Niigata, thank you for uploading the video. …m(_ _)m This sound source is Prelude No. 2 in C minor, BWV847, which is included in Disc-1 of ``JS-Bach-Well-Tempered Clavier'', a two-disc SACD hybrid album by harpsichordist Mayako Sone. The CD layer was ripped at Flac24bit/176.4Khz using Rin Records' paid software "dBpoweramp", and after removing jitter, it was up-converted to a DSD 5.6MHz DSF file using KORG's paid software Audio Gate. Then, the clean data with jitter removed was loaded into the shareware software Bughead, an ultra-high-quality digital audio player created by the genius Orya.

元新潟のUさん、動画をUPしていただき有難う御座います。…m(_ _)m この音源はチェンバリスト 曽根 麻矢子嬢のSACDハイブリット盤2枚組アルバムである- 「JS-バッハ-平均律クラヴィーア曲集」 のDisc-1に入っている、 第2番 ハ短調 BWV847;前奏曲 です。 CD層をリンレコード社の有料ソフトウエアの「dBpoweramp」を用いまして、Flac24bit/176.4Khzでリッピングし、ジッター除去後KORG社の有料ソフトのオーディオゲートを用い、DSD5.6MHzのDSFファイルにUPコンバートして更にジッター除去を行ったクリーンなデータを、天才おりゃさんの超高音質デジタルオーディオプレーヤーであるシェアウエアソフトのBughead に読み込んで再生した再生音を、オーディオ・オフ会においで下さった「元新潟のUさん」が空気録音された物を、こうしてUPして下さった動画です。 Mr. U, formerly of Niigata, thank you for uploading the video. …m(_ _)m This sound source is Prelude No. 2 in C minor, BWV847, which is included in Disc-1 of ``JS-Bach-Well-Tempered Clavier'', a two-disc SACD hybrid album by harpsichordist Mayako Sone.

UP.していただき、有難う御座います。…m(_ _)m 画面の右上に、各周波数段階での音圧を表示して下さっているので、この録音データーの音圧が…50Hz=40Hz=30Hz…とフラット=同じ音圧である事がお解り頂けると思います。 実は、16Hzまでフラットに再生できていますので、このL・TQWTのSP.システムでは、パイプオルガンの最低音も、ベーゼンドルファー・インペリアルの97鍵の左端の最低音も、勿論、スタインウエイのD475の88鍵の左端の27.5Hzも、しっかり再生できます。 それが「本来の音」であり「本当の音」なのです。 つまり、サンサーンスの第3番「オルガン付き」も、難曲で知られるモーリス・ラヴェルの「夜のガスパール」も、バッハの「オルガン曲全集」も、どんとこいです!…😊 参考:① x.com/AmisRavelJapon/status/1304670280837521410 参考:② >ベーゼンドルファー・インペリアルは97鍵(8オクターブ)を備える。これは92鍵(最低音F0)を有するベーゼンドルファー225とは大きく異なっている。ピアノの低音部(すなわち左側)の追加鍵盤は88鍵ピアノの通常の鍵盤と区別できるように黒色をしている。元々はピアニストがうっかりと余分な音を弾かないように取り外し可能なパネルで覆われていた。これらの鍵盤はほとんど使われることはないものの、追加の低音弦は全体の豊かな音色に寄与する追加の倍音共鳴を作り出す。追加鍵盤を利用することが意図された楽曲も作曲されている<(なお、ベーゼンドルファー・インペリアルは価格 41,910,000 円(税込)) 参考:③ piano.miki.co.jp/lineup/model-290-imperial/ この領域になると、アナログ・レコードではアームとカンチレバーの共振干渉と、原盤のカッティングに於ける「溝振り幅制限」で、記録も再生も困難ですね。 勿論、アナログ・テープならば無問題です。 Thank you for uploading it. …m(_ _)m The sound pressure at each frequency level is displayed at the top right of the screen, so you can see that the sound pressure of this recording data is flat = the same sound pressure as 50Hz = 40Hz = 30Hz...

チェンバロは再生が難しい楽器の一つだと思います。 通奏低音にも使用される様に、低音域が得意な楽器ですが、弦をひっかく撥弦楽器ならではの低域の切れ味が肝ですね! 鈍重な大口径ウーファでは、この鋭い低音域の立ち上がりが再生出来るかが肝の一つだと思います。 もう一つの肝は、チェンバロが置かれている「場」の再現です。 このSACDハイブリット盤には、録音時の現場の、超低域の暗騒音も入っています。 20Hzまでフラットに再生すると、演奏前にこの「場」が部屋に現れます。 40Hzまでの再生能力ではこの「場」は現れません。 I think the harpsichord is one of the most difficult instruments to play. It is an instrument that specializes in the low range, as it is also used for basso continuo, but the sharpness in the low range that is unique to a plucked string instrument is the key! I think one of the most important aspects of a sluggish, large-diameter woofer is whether it can reproduce this sharp rise in the bass range. Another important point is the reproduction of the ``place'' where the harpsichord is placed. This SACD hybrid disc also includes ultra-low-range background noise from the recording site. When played flat to 20Hz, this "field" appears in the room before the performance. This "field" does not appear with playback ability up to 40Hz.
