effect

This is an effect demo.

• A Button: Plays the sequence sound
• X Button: Plays the wave sound
• Y Button: Plays the stream sound
• B Button: Stops the sound

• Right Button, Left Button: Switches the effect

Demo to implement the following effects.

• nw::snd::FxReverb
• nw::snd::FxDelay
• nn::snd::FxReverb
• nn::snd::FxDelay

Main flow is in the order: set effect parameters, secure work memory, allocate work memory, register effect, remove effect, and release work memory.

    // nw::snd::FxReverb settings
    {
        // Parameter settings
        nw::snd::FxReverb::FilterSize filterSize;
        filterSize.m_Comb0 = 20 * 160;
        filterSize.m_Comb1 = 30 * 160;
        filterSize.m_AllPass = 13 * 160;

        m_NwFxReverbParam.m_EarlyReflectionTime = 300;
        m_NwFxReverbParam.m_FusedTime = 1000;
        m_NwFxReverbParam.m_PreDelayTime = 200;
        m_NwFxReverbParam.m_pFilterSize = &filterSize;

        m_NwFxReverb.SetParam( m_NwFxReverbParam );

        // Secure work memory
        size_t reverbBufferSize = m_NwFxReverb.GetRequiredMemSize();
        m_pMemoryForNwFxReverb = MemAlloc( reverbBufferSize, 4 );

        // Allocate work memory
        m_NwFxReverb.AssignWorkBuffer(
                reinterpret_cast( m_pMemoryForNwFxReverb ),
                reverbBufferSize );
    }

    // Register effect
    nw::snd::SoundSystem::AppendEffect( nw::snd::AUX_BUS_A, &m_NwFxReverb );

    // Remove effect
    nw::snd::SoundSystem::ClearEffect( nw::snd::AUX_BUS_A, 0 );

    // Release work memory
    m_NwFxReverb.ReleaseWorkBuffer();
