P\u0159edstavuji prvn\u00ed verzi metronomu IronTick. Je to lehk\u00fd, p\u0159esn\u00fd, multiplatformn\u00ed metronom zalo\u017een\u00fd na frameworku Qt6. Vyzna\u010duje se t\u00edm, \u017ee generuje nep\u0159etr\u017eit\u00fd zvukov\u00fd proud s kliknut\u00edmi m\u00edsto toho, aby p\u0159ehr\u00e1val jednotliv\u00e9 kliknut\u00ed podle \u010dasova\u010de, jak to d\u011bl\u00e1 v\u011bt\u0161ina ostatn\u00edch program\u016f metronomu. D\u00edky tomuto p\u0159\u00edstupu klik\u00e1 IronTick mnohem stabiln\u011bji a p\u0159esn\u011bji, i p\u0159i velk\u00e9 z\u00e1t\u011b\u017ei na pozad\u00ed.<\/p>\n

Mo\u017enosti a vlastnosti:<\/h2>\n
    \n
  1. \n

    Vysok\u00e1 p\u0159esnost: stabiln\u00ed kliknut\u00ed, p\u0159esn\u00e9 udr\u017eov\u00e1n\u00ed tempa.<\/p>\n<\/li>\n

  2. \n

    Podpora r\u016fzn\u00fdch takt\u016f: z\u00e1kladn\u00ed takty (2\/4, 3\/4, 4\/4, 6\/8), a tak\u00e9 mo\u017enost nastavit jak\u00fdkoli jin\u00fd takt.<\/p>\n<\/li>\n

  3. \n

    Vizualizace: ukazatel siln\u00fdch a slab\u00fdch dob.<\/p>\n<\/li>\n

  4. \n

    Ovl\u00e1d\u00e1n\u00ed tempa: zm\u011bna tempa, spu\u0161t\u011bn\u00ed a zastaven\u00ed metronomu je mo\u017en\u00e9 pomoc\u00ed jedn\u00e9 kl\u00e1vesnice, bez my\u0161i.<\/p>\n<\/li>\n<\/ol>\n

    Jak\u00e9 probl\u00e9my \u0159e\u0161\u00ed<\/h2>\n

    Rozhodl jsem se vyvinout tuto aplikaci, proto\u017ee jsem se setkal s v\u00e1\u017en\u00fdm probl\u00e9mem v\u011bt\u0161iny st\u00e1vaj\u00edc\u00edch programov\u00fdch metronom\u016f \u2013 \u010dasto nedok\u00e1\u017eou p\u0159esn\u011b udr\u017eet tempo a vynech\u00e1vaj\u00ed \u00fadery. Situace se v\u00fdrazn\u011b zhor\u0161uje na slab\u00fdch stroj\u00edch p\u0159i vysok\u00e9m zat\u00ed\u017een\u00ed. Kdy\u017e jsem se za\u010dal zab\u00fdvat p\u0159\u00ed\u010dinami tohoto chov\u00e1n\u00ed, uk\u00e1zalo se, \u017ee typick\u00fd p\u0159\u00edstup k implementaci t\u011bchto metronom\u016f spo\u010d\u00edv\u00e1 v vytvo\u0159en\u00ed \u010dasova\u010de, na jeho\u017e aktivaci se spou\u0161t\u00ed p\u0159ehr\u00e1v\u00e1n\u00ed kr\u00e1tk\u00e9ho zvuku \u00faderu. Tady je odpov\u011b\u010f, proto\u017ee to v\u0161echno funguje v multitaskingov\u00e9m opera\u010dn\u00edm syst\u00e9mu, \u010dasova\u010de v u\u017eivatelsk\u00fdch procesech negarantuj\u00ed fungov\u00e1n\u00ed v re\u00e1ln\u00e9m \u010dase s p\u0159esnost\u00ed p\u0159ijatelnou pro hudebn\u00edky. Periodicky \u010dasova\u010d aktivuje sign\u00e1l mnohem pozd\u011bji, ne\u017e je po\u017eadovan\u00fd \u010das.<\/p>\n

    Tento probl\u00e9m je v IronTick vy\u0159e\u0161en velmi jednodu\u0161e \u2013 syntetizuje nep\u0159etr\u017eit\u00fd PCM proud audiosampl\u016f, do kter\u00e9ho jsou p\u0159esn\u011b v pot\u0159ebn\u00fdch m\u00edstech vlo\u017eeny zvuky \u00fader\u016f. Tento proud je nep\u0159etr\u017eit\u011b p\u0159ehr\u00e1v\u00e1n zvukovou kartou, jako ka\u017ed\u00fd audio proud, nap\u0159\u00edklad p\u00edse\u0148 v audio p\u0159ehr\u00e1va\u010di. U v\u00e1s p\u0159ece p\u00edse\u0148 v p\u0159ehr\u00e1va\u010di ne\u0161kube periodicky, bez ohledu na to, jak\u00fd program je na pop\u0159ed\u00ed a jak\u00e9 je zat\u00ed\u017een\u00ed? Tak\u017ee metronom funguj\u00edc\u00ed na tomto principu klapk\u00e1 tak stabiln\u011b, jak audio p\u0159ehr\u00e1va\u010d p\u0159ehr\u00e1v\u00e1 skladbu. Pro to nepot\u0159ebuje nep\u0159esn\u00fd \u010dasova\u010d.<\/p>\n

    Druh\u00fd probl\u00e9m, kter\u00fd je u\u017e m\u00e9n\u011b d\u016fle\u017eit\u00fd \u2013 obvykle je nepohodln\u00e9 m\u011bnit tempo, ani\u017e byste uvolnili kytaru. Proto je v IronTick z v\u00fdroby implementov\u00e1no kl\u00e1vesov\u00e9 ovl\u00e1d\u00e1n\u00ed jednou kl\u00e1vesou (skute\u010dn\u011b pouze jednou, nen\u00ed t\u0159eba dr\u017eet \u201eakordy\u201c) pro z\u00e1kladn\u00ed funkce. Tak\u00e9 je mo\u017en\u00e9 nastavit krok zvy\u0161ov\u00e1n\u00ed\/sni\u017eov\u00e1n\u00ed tempa. Pou\u017e\u00edv\u00e1m to tak, \u017ee za\u010d\u00edn\u00e1m tr\u00e9novat pas\u00e1\u017e s pomal\u00fdm tempem, nap\u0159\u00edklad 120 bpm, a ob\u010das zm\u00e1\u010dknu kl\u00e1vesu J, abych zv\u00fd\u0161il bpm o 5 jednotek. Potom je\u0161t\u011b o 5, a tak d\u00e1le. M\u016f\u017eete nastavit jak\u00fdkoliv krok. Stisknout jedno tla\u010d\u00edtko je snadn\u00e9, ani\u017e bych uvolnil trs\u00e1tko.<\/p>\n
