- **PCM Generator**: Record microphone input and convert it to Base64-encoded PCM.
  - Supports various sample rates (8kHz - 48kHz).
  - Supports Mono/Stereo.
  - Supports 8-bit, 16-bit (signed), and 32-bit (float) formats.
- **Packet Player**: Decode and play back Base64 PCM strings.
  - Paste multiple sequential packets to test streaming audio flows.
  - Handles different PCM formats and sample rates.
