Shadertoy exposes audio through a 512x2 texture, where the first row is the spectrum, and second row is wave data.

Pixel format is GL_RED GL_UNSIGNED_BYTE, meaning that each pixel contains only one 8-bit channel.

According to this shader from iq the audio in the browser is supposed to have a samplerate of 48kHz, but as it turns out, that's not the case: most likely it will be in 44.1kHz.

The LSM9DS0 is a versatile 9DOF sensor. It has a built-in

1. The texture target needs to be GLES20.GL_TEXTURE_EXTERNAL_OES instead of GL_TEXTURE_2D, e.g. in the glBindTexture calls and glTexParameteri calls.

2. In the fragment shader define a requirement to use the extension:
#extension GL_OES_EGL_image_external : require

3. For the texture sampler used in the fragment shader, use samplerExternalOES instead of sampler2D.

Everything below here is all in the C code, no more Java.

4. In the C code, use glEGLImageTargetTexture2DOES(GL_TEXTURE_EXTERNAL_OES, eglImage) to specify where the data is, instead of using glTexImage2D family of functions.
