Pour qui a connu ce support, la chose est, pour le moins, surprenante ! Pour les plus jeunes, il faudra rappeler qu\u2019\u00e0 la fin des ann\u00e9es 70 et au d\u00e9but des ann\u00e9es 80, les cassettes pr\u00e9enregistr\u00e9es se vendaient mieux que les 33 tours, auto-radio et mode du WalkMan –un genre d\u2019iPod de l\u2019\u00e9poque\u2026<\/em>– obligent, et qu\u2019on pouvait acheter des cassettes vierges sur lesquelles on enregistrait, \u00e0 usage priv\u00e9 bien entendu, les 33 tours des amis et des m\u00e9diath\u00e8ques.<\/p>\n

\"\"<\/a>Sauf que la qualit\u00e9 sonore \u00e9tait d\u00e9grad\u00e9e du fait m\u00eame du support magn\u00e9tique : une fine bande d\u00e9filant lentement –4,75 cm par seconde<\/em>-, ce qui engendrait, outre une bande pesante \u00e9court\u00e9e dans l\u2019aigu -les premi\u00e8res atteignaient p\u00e9niblement les 12 kHz et c\u2019est seulement les platines tr\u00e8s co\u00fbteuses qui permettait de d\u00e9passer les 16 kHz, ce palier \u00e9tant d\u00e9pass\u00e9 assez tardivement dans l\u2019histoire de ce support-, un souffle non n\u00e9gligeable. Les derniers artifices de r\u00e9duction de bruit, et notamment le fameux Dolby C, \u00e9taient \u00e0 peu pr\u00e8s parvenus \u00e0 limiter ce dernier d\u00e9sagr\u00e9ment. N\u00e9anmoins, les t\u00eates des lecteurs-enregistreurs de cassettes avaient tendance \u00e0 s\u2019encrasser relativement rapidement -il fallait les nettoyer au coton-tige et \u00e0 l\u2019alcool, mais \u00e9galement les d\u00e9magn\u00e9tiser r\u00e9guli\u00e8rement- et les ph\u00e9nom\u00e8nes de pleurage n\u2019\u00e9taient pas rares, les courroies d\u2019entra\u00eenement du m\u00e9canisme n\u2019\u00e9tant pas inusables.<\/p>\n

Tr\u00e8s honn\u00eatement, un fichier \u2022mp3, m\u00eame compress\u00e9 \u00e0 128 kbits, est nettement sup\u00e9rieur, d\u2019autant que les codecs de compression ont \u00e9volu\u00e9 tr\u00e8s favorablement depuis l\u2019apparition de ce format, \u00e0 la fin des ann\u00e9es 90.<\/p>\n

<\/a>Je n\u2019ai donc aucune nostalgie de la chose. Mon autoradio n\u2019accepte plus les cassettes depuis une bonne douzaine d\u2019ann\u00e9es et je n\u2019ai plus de WalkMan depuis encore bien plus longtemps. Je me souviens par contre avec fiert\u00e9 de ma tr\u00e8s performante platine-cassettes<\/strong><\/span><\/a>\u00a0–cliquer sur limage pour la voir en\u00a0plus grand<\/em>-qui offrait une bande passante fr\u00f4lent les 18 kHz sur des bandes \u00ab\u00a0normales\u00a0\u00bb et les 19,5 kHz avec des bandes au chrome –celles qui sont pr\u00e9sent\u00e9es sur l\u2019image accompagnant cette notule : le \u00ab\u00a090\u00a0\u00bb indique que la dur\u00e9e de la cassette est de 90 minutes, soit 45 minutes par face. Il existait aussi des C60 pour 60 minutes et des C120 pour 120 minutes, mais ces derni\u00e8res avaient tendance \u00e0 \u00ab\u00a0faire des nouilles\u00a0\u00bb, la bande \u00e9tant trop longue pour le support<\/em>-, le tout en proposant un excellent rapport signal \/ bruit –mesure du niveau de souffle<\/em>-.<\/p>\n

Mais, de l\u00e0 \u00e0 la regretter, il y a un pas que je ne franchirai pas ! La nostalgie, camarade\u2026<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
