C++ (Cpp) audioContext Examples

Example #1

File: AudioContext.cpp Project: huningxin/blink-crosswalk

PassRefPtr<AudioContext> AudioContext::create(Document* document)
{
    ASSERT(document);
    ASSERT(isMainThread());
    if (s_hardwareContextCount >= MaxHardwareContexts)
        return 0;

    RefPtr<AudioContext> audioContext(adoptRef(new AudioContext(document)));
    audioContext->suspendIfNeeded();
    return audioContext.release();
}

Example #2

File: AudioContext.cpp Project: Happy-Ferret/webkit.js

PassRefPtr<AudioContext> AudioContext::create(Document& document, ExceptionCode& ec)
{
    UNUSED_PARAM(ec);

    ASSERT(isMainThread());
    if (s_hardwareContextCount >= MaxHardwareContexts)
        return nullptr;

    RefPtr<AudioContext> audioContext(adoptRef(new AudioContext(document)));
    audioContext->suspendIfNeeded();
    return audioContext.release();
}

Example #3

File: AudioContext.cpp Project: ZECTBynmo/LabSound

PassRefPtr<AudioContext> AudioContext::createOfflineContext(Document* document, unsigned numberOfChannels, size_t numberOfFrames, float sampleRate, ExceptionCode& ec)
{
    ASSERT(document);

    // FIXME: offline contexts have limitations on supported sample-rates.
    // Currently all AudioContexts must have the same sample-rate.
    HRTFDatabaseLoader* loader = HRTFDatabaseLoader::loader();
    if (numberOfChannels > 10 || !isSampleRateRangeGood(sampleRate) || (loader && loader->databaseSampleRate() != sampleRate)) {
        ec = SYNTAX_ERR;
        return 0;
    }

    RefPtr<AudioContext> audioContext(adoptRef(new AudioContext(document, numberOfChannels, numberOfFrames, sampleRate)));
    audioContext->suspendIfNeeded();
    return audioContext.release();
}

Example #4

File: OfflineAudioContext.cpp Project: windyuuy/opera

PassRefPtr<OfflineAudioContext> OfflineAudioContext::create(ScriptExecutionContext* context, unsigned numberOfChannels, size_t numberOfFrames, float sampleRate, ExceptionCode& ec)
{
    // FIXME: add support for workers.
    if (!context || !context->isDocument()) {
