Draw an AudioThumbnail from binary data

[tobante]

Hi,

quick question: I’m trying to render wav files which are bundled as binary data. As far as I can tell, the interface for AudioThumbnail only provides setReader & setSource methods, which only work on files. I’m probably missing something really obvious. How do I connect a MemoryInputStream to a AudioThumbnail?

Thanks,

tobante

You should be able to call loadFrom with your AudioThumbnail instance.

But the docs say: This is not an audio file stream! It takes a stream of thumbnail data that would previously have been created by the saveTo() method.

Sure, so you can store the data that was generated by saveTo into a file which can be embedded.

Could you just use an inmemory Reader?

Can I create an `juce::AudioFormatReader` from a buffer instead of a `juce::File`?

Below is an excerpt from the SamplerPluginDemo demo. //============================================================================== inline std::unique_ptr<AudioFormatReader> makeAudioFormatReader (AudioFormatManager& manager, const void* sampleData, size_t dataSize) { return std::unique_ptr<AudioFormatReader> (manager.createReaderFor (std::make_unique<MemoryInp…
