  6. What subjective comparison did the SoundStream paper report at 3 kbps?
    • At 24 kHz, SoundStream at 3 kbps outperformed Opus at 12 kbps in the reported evaluation
    • It matched every codec at every bitrate
    • It was tested only against MP3 at 320 kbps
    • It produced higher quality than all commercial audio codecs
  7. What is the decoder’s role in a neural audio codec?
    • Choose which transcript is legally correct
    • Predict the speaker’s identity from text only
    • Reconstruct audio from the encoded discrete representation
    • Assign language labels to silence
  8. What inference capability did the SoundStream paper report for its low-latency codec?
    • Only offline batch processing on a server cluster
    • It required a GPU for every audio frame
    • It could encode images but not audio
    • Streamable real-time inference on a smartphone CPU
