ManagedBass.Gapless 0.2.0

BASS_GAPLESS

A gapless playback plugin for BASS with .NET bindings.

bass.dll is required for native projects. ManagedBass is required for .NET projects.

A simple example;

var sourceChannel1 = Bass.CreateStream(Path.Combine(Location, "Media", "01 Botanical Dimensions.m4a"), Flags: BassFlags.Decode);
var sourceChannel2 = Bass.CreateStream(Path.Combine(Location, "Media", "02 Outer Shpongolia.m4a"), Flags: BassFlags.Decode);

BassGapless.ChannelEnqueue(sourceChannel1);
BassGapless.ChannelEnqueue(sourceChannel2);

var channelInfo = Bass.ChannelGetInfo(sourceChannel1);
var playbackChannel = BassGapless.StreamCreate(channelInfo.Frequency, channelInfo.Channels, flags);

Bass.ChannelPlay(playbackChannel);

while (Bass.ChannelIsActive(playbackChannel) == PlaybackState.Playing)
{
    Thread.Sleep(1000);
}

Bass.StreamFree(sourceChannel1);
Bass.StreamFree(sourceChannel2);
Bass.StreamFree(playbackChannel);

Streams added to the queue must have the same rate/channels as the gapless stream.

Addon libs for ASIO/CD are included, place them in your addon folder if required. All libs can also be manually loaded;

BassGapless.Load();
BassGapless.Asio.Load();
BassGapless.Cd.Load();

ASIO example;

var sourceChannel1 = Bass.CreateStream(Path.Combine(Location, "Media", "01 Botanical Dimensions.m4a"), Flags: BassFlags.Decode);
var sourceChannel2 = Bass.CreateStream(Path.Combine(Location, "Media", "02 Outer Shpongolia.m4a"), Flags: BassFlags.Decode);

BassGapless.ChannelEnqueue(sourceChannel1);
BassGapless.ChannelEnqueue(sourceChannel2);

var channelInfo = Bass.ChannelGetInfo(sourceChannel1);

 BassGapless.Asio.ChannelEnable(false, 0);
 BassAsio.ChannelJoin(false, 1, 0);
 BassAsio.ChannelSetFormat(false, 0, AsioSampleFormat.Bit16)
 BassAsio.ChannelSetRate(false, 0, channelInfo.Frequency)

 BassAsio.Start()

while (Bass.ChannelIsActive(sourceChannel1) == PlaybackState.Playing || Bass.ChannelIsActive(sourceChannel2) == PlaybackState.Playing)
{
    Thread.Sleep(1000);
}

BassAsio.Stop();
Bass.StreamFree(sourceChannel1);
Bass.StreamFree(sourceChannel2);

CD example;

BassGapless.SetConfig(BassGaplessAttriubute.RecycleStream, true);
BassGapless.Cd.Enable(0, BassFlags.Decode);

var sourceChannel = BassCd.CreateStream(0, 0, BassFlags.Decode);

var channelInfo = Bass.ChannelGetInfo(sourceChannel1);
var playbackChannel = BassGapless.StreamCreate(channelInfo.Frequency, channelInfo.Channels, flags);

Bass.ChannelPlay(playbackChannel);

while (Bass.ChannelIsActive(playbackChannel) == PlaybackState.Playing)
{
    Thread.Sleep(1000);
}

BassGapless.Cd.Disable();
Bass.StreamFree(sourceChannel);
Bass.StreamFree(playbackChannel);
