Concurrent real-time interface for multimedia engines

The crime crate is useful for real-time multimedia applications for providing different output audio formats where the input is a stream of samples, typically coming from a machine-learning model which generates a fixed amount of samples in fp32.

This crate operates entirely on streams, provides delay compensation for each supported operation, and thus eliminates the need for providing padding and/or flushing the buffer. The first audio signal in the input is guaranteed to correspond to the first audio signal in the output, and likewise for the last signal.

Current functionalities:

• Input and outputs in futures::Stream.
• Resampling.
• Streaming audio codec (PCM, WAV, MP3).
• Time scaling (using WSOLA).

Supported codecs:

• Headerless sample stream
  • Linear PCM (i16, f16, f32, all little-endian)
  • G.711 μ-law
• MP3
• WAV
  • Linear PCM (i16, f16, f32, all little-endian)
