L’ann\u00e9e derni\u00e8re, \u00e0 peu pr\u00e8s \u00e0 la m\u00eame \u00e9poque, je vous parlais de l’histoire en jaune<\/a><\/strong><\/span>, qui permettait de reconstruire un peu de la saga de l’enregistrement audio. Aujourd’hui, je vous propose quelques petites histoires en lien avec les premiers enregistrements r\u00e9ellement Hi-Fi, au sortir de la seconde guerre mondiale.<\/p>\n

\"ffrrdecca\"<\/a>Deux ph\u00e9nom\u00e8nes majeurs permirent de passer progressivement de l’\u00e8re du 78T \u00e0 celle du 33T : \u2022 d’une part, l’enregistrement sur bandes magn\u00e9tiques<\/strong>, mis en oeuvre tr\u00e8s t\u00f4t en Allemagne –la qualit\u00e9 des retransmissions radio allemande interpellait les Europ\u00e9ens des pays alentours et, surtout, la bande magn\u00e9tique permit d’enregistrer les oeuvres d’un seul tenant, et non pas par \u00ab\u00a0bouts de 4 minutes\u00a0\u00bb<\/em>-; d’autre part, l’am\u00e9lioration des microphones<\/strong>, qui est due aux Anglais, en lien direct avec les syst\u00e8mes acoustiques de d\u00e9tection des sous-marins ennemis pendant la guerre : cette technologie fut reprise par la marque anglaise Decca d\u00e8s 1944, et popularis\u00e9e sous le terme de \u00ab\u00a0ffrr\u00a0\u00bb, soit full frequency range recordings<\/em>.<\/p>\n

\"ffrrdeccaLP\"<\/a>Le premier enregistrement r\u00e9pondant quasiment aux normes Hifi<\/strong> –enregistrement encore mono, certes, mais proposant une<\/em>\u00a0bande passante consid\u00e9rablement \u00e9largie et s’\u00e9tendant de 80 \u00e0 14000 Hz<\/em>-, tr\u00e8s sup\u00e9rieur aux enregistrements r\u00e9alis\u00e9s par la concurrence de l’\u00e9poque, eut lieu \u00e0 Londres en 1945 : il s’agit de la 5\u00e8me symphonie de Tchaikovsky par le National Symphony Orchestra, sous la direction de Sidney Beer. Vous pouvez en \u00e9couter des extraits<\/a><\/strong><\/span>, pour vous rendre compte de la qualit\u00e9 sonore obtenue eu \u00e9gard aux standards moyens de l’\u00e9poque –le disque est cependant hors catalogue depuis longtemps, et difficilement trouvable, et son int\u00e9r\u00eat artistique est plut\u00f4t mineur<\/em>-.<\/p>\n

\"MilsteinWalter\"<\/a>Une fois cette technologie appropri\u00e9e, il fallait encore passer du 78T –4 minutes par face<\/em>– au 33T \u00ab\u00a0long player\u00a0\u00bb, dit LP. C’est gr\u00e2ce \u00e0 l’enregistrement sur bandes magn\u00e9tiques que ce passage fut consid\u00e9rablement simplifi\u00e9, puisque le montage ne posait plus, d\u00e9sormais, de probl\u00e8mes insurmontables. Le premier 33T LP \/ 30cm de l’histoire du disque<\/strong> fut r\u00e9alis\u00e9 par Columbia records. Il s’agit du concerto pour violon de Mendelssohn, dans la version de Nathan Milstein dirig\u00e9 par Bruno Walter. Hors classique, le tout premier LP produit \u00e9tait \u00ab\u00a0The voice of Frank Sinatra\u00a0\u00bb.<\/p>\n

Il va sans dire que, rapidement, l’ensemble du catalogue 78T commen\u00e7a \u00e0 dispara\u00eetre, au\u00a0profit du nouveau standard infiniment plus pratique propos\u00e9 par le LP.<\/p>\n

C’est alors que l’histoire \u00ab\u00a0moderne\u00a0\u00bb de l’enregistrement audio put commencer.<\/p>\n","protected":false},"excerpt":{"rendered":"
