Přehrátí dvou wav souborů zároveň (paralelně) – .NET – Fórum – Programujte.com

Ahoj
nevíte prosím jak spustit v C# dva soubory wave zaroveň? Paralelně... Vždy když mi jeden zvuk běží, a dám spustit druhý, tak se ten původní ukončí a spustí jen ten druhý.

díky

Musíš použít více vláken, viz seriál tady na Programujte.

using System.Runtime.InteropServices;



private byte[] sound = File.ReadAllBytes("tada.wav");





[DllImport("winmm.dll")]

        private static extern bool PlaySound(byte[] memory, int module, int flags);

    

        const int SND_SYNC = 0x0000;

        const int SND_ASYNC = 0x0001;

        const int SND_NODEFAULT = 0x0002;

        const int SND_MEMORY = 0x0004;

        const int SND_LOOP = 0x0000;

        const int SND_NOSTOP = 0x0010;

        const int SND_NOWAIT = 0x00002000;

        const int SND_FILENAME = 0x00020000;

        const int SND_RESOURCE = 0x00040004;

        const int SND_PURGE = 0x0040;

        const int SND_APPLICATION = 0x0080;

        

        /// <summary>

        /// asynchroni prehrani zvuku

        /// </summary>

        private void play()

        {

            PlaySound(sound, 0, SND_MEMORY | SND_ASYNC | SND_LOOP);

        }

To Chrasty: ale kdyz nemam vicejadrovy procesor tak ty vlakna nepobezi zaraz ne?

to zdarovka: vyzkousim

ted sem se registroval takze zdarovka sem ja.....ale myslim ze to funguje jenom na wav soubory

OK a z kama ci cerpal? ja nevidm presne kam mam umistit o kodu ty definice konstant, jestli primo do tridy nebo jinde?

ja to mel primo v kodu mezi metodamy, tak jak to vidis

Tak jsem to zkusil jak si mi rikal,
pridefinoval jsem i druhy soubor

        private byte[] sound = File.ReadAllBytes(@"C:\Users\Honza\Desktop\mujSong.wav");

        private byte[] sound2 = File.ReadAllBytes(@"C:\Users\Honza\Desktop\Track6.wav");



...



       public Form1()

        {

            InitializeComponent();

            play();

            play2();

        }



        private void play()

        {

            PlaySound(sound, 0, SND_MEMORY | SND_ASYNC | SND_LOOP);

        }



        private void play2()

        {

            PlaySound(sound2, 0, SND_MEMORY | SND_ASYNC | SND_LOOP);

        }

zkus ty dve metody sloucit do jedne melo by to fungovat

        public Form1()

        {

            InitializeComponent();

            play();

        }



        private void play()

        {

            PlaySound(sound, 0, SND_MEMORY | SND_ASYNC | SND_LOOP);

            PlaySound(sound2, 0, SND_MEMORY | SND_ASYNC | SND_LOOP);

        }

tak ted uz taky nevim...todle jsem nevymejslel, to nam ucitel akorat ukazoval jak si pridat zvuk do nasich praci.....sam sem to nevymyslel, ale kazdopadne by to melo jit tim multithreadingem, vice jadrovy procesor na to nepotrebujes jak si se ptal
kdyz si pridas

using System.Threading;

Zkus to s těmi vlákny, mělo by to fungovat.

        public Form1()

            Thread u = new Thread(new ThreadStart(play));

            Thread v = new Thread(new ThreadStart(play2));

             u.start();

             v.start();

        }

To Honza : Tak to nevím, zkuste ty soubory prohodit...

Tak abych tu pridal i nejake vysledky...

Tak jsem to vyresil zpusobem, ze jsem projekt vytvoril ve WPF, vlozil zvukove stopy jako mediaelement a ty pak muzu jednotuse spustit pomoci "xxx.play"

takze diky Vam kteri jste se mi snazili pomoct.
