Stable Audio Latent Diffusion Quiz

Answers and explanations appear as you take the quiz.

1. What core technique does Stable Audio use to generate audio?
   • Rule-based MIDI sequencing
   • Autoregressive token prediction only
   • Latent diffusion in a compressed audio space
   • Direct waveform recording
2. What timing information conditions the original Stable Audio research setup?
   • Start position and total-duration signals
   • Only a singer’s legal name
   • Only a video display resolution
   • Only the output filename’s alphabetical position
3. What component compresses the raw audio into a latent representation?
   • A spell checker
   • A random number generator
   • A speech-to-text engine
   • A variational autoencoder (VAE)
4. What capability did the official April 2024 Stable Audio 2.0 announcement report?
   • A guarantee of six-minute generation in the original 95 sec paper setup
   • Up to three-minute 44.1 kHz stereo generation and audio-to-audio transformation
   • Only silent mono waveform output
   • Only automatic subtitle translation
5. How does a text-only generation run in the original latent-diffusion setup start?
   • From a noise latent that is denoised using the conditions
   • By necessarily recording a live microphone
   • By copying a complete training song without a model
   • By requiring a complete future waveform as input
6. Which text encoder is identified in the original Fast Timing-Conditioned Latent Audio Diffusion architecture?
   • Only a handwritten MIDI rule table
   • A required raw image-pixel encoder
   • An unspecified choice guaranteed identical across all versions
   • A CLAP text encoder
7. At 44.1 kHz stereo, how many individual channel amplitude values occur in one second before file encoding?
   • 44,100
   • 88,200
   • 22,050
   • 176,400
8. In the original 95-second window example, a 30-second requested signal is followed by how much silence before trimming?
   • 30 seconds
   • 95 seconds
   • 65 seconds
   • 125 seconds
