Update Imagen2 to Imagen, change example prompt text, and remove multi-speaker audio generation section to simplify documentation.
Enhances readability by formatting the provider-specific configuration note as a proper note block in the models documentation.
Update the models.mdx documentation to enhance the media generation section with better formatting, clearer explanations, and improved code examples for both image and audio generation.

did you test this? I don't think this would work because gemini returns audio in PCM format, it needs to be converted to WAV. Ex:
// npm i wav && npm i --save-dev @types/wav
import wav from 'wav';
async function saveWaveFile(
filename: string,
pcmData: Buffer,
channels = 1,
rate = 24000,
sampleWidth = 2
) {
return new Promise((resolve, reject) => {
const writer = new wav.FileWriter(filename, {
channels,
sampleRate: rate,
bitDepth: sampleWidth * 8,
});
writer.on('finish', resolve);
writer.on('error', reject);
writer.write(pcmData);
writer.end();
});
}

this is my experience with GenAI sdk testing of audio you need to convert using code in your app

Yeah, I forgot to include the converter function from the sample...
Ugh, that's ugly.
