Audio Handling

// Example: Pre-upload validation
if (audioFile.size > 1024 * 1024 * 1024) { // 1GB in bytes
  console.error('File size exceeds 1GB limit');
  return;
}

// Recommended settings for different use cases
const audioSettings = {
  podcast: { format: 'mp3', bitrate: 128, channels: 1 }, // mono
  music: { format: 'aac', bitrate: 256, channels: 2 },   // stereo
  voiceNote: { format: 'opus', bitrate: 64, channels: 1 } // mono, low bitrate
};

// Example: Upload with user feedback
const uploadWithFeedback = async (audioFile: File) => {
  setUploading(true);
  setProgress(0);
  
  try {
    const result = await uploadAudio(audioFile, {
      onProgress: (percent) => setProgress(percent)
    });
    showSuccess('Audio uploaded successfully!');
    return result;
  } catch (error) {
    showError(getErrorMessage(error));
  } finally {
    setUploading(false);
  }
};

// Example: Retry logic with exponential backoff
async function uploadWithRetry(audioFile: File, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await uploadAudio(audioFile);
    } catch (error) {
      if (i === maxRetries - 1) throw error;
      await delay(Math.pow(2, i) * 1000); // Exponential backoff
    }
  }
}

// Example: Error handling with specific actions
try {
  await uploadAudio(file);
} catch (error) {
  switch (error.code) {
    case 'FILE_SIZE_EXCEEDED':
      return compressAndRetry(file);
    case 'DURATION_EXCEEDED':
      return suggestSplitting(file);
    case 'UNSUPPORTED_FORMAT':
      return suggestConversion(file);
    case 'NETWORK_ERROR':
      return retryWithBackoff(file);
    default:
      return showGenericError(error);
  }
}

// Check metadata after upload
if (!audioData.attributes?.metadata?.duration) {
  console.warn('Duration metadata missing - may need to re-encode');
}

// Validate audio quality settings
const isQualityAcceptable = (metadata: AudioMetadata) => {
  return metadata.bit_rate >= 64000 && // At least 64 kbps
         [44100, 48000].includes(metadata.sample_rate); // Standard sample rates
};
