TCR is a numerical code based on the Classical Theory or Reverberation.
The simulation code TCR (from French "Théorie Classique de la Réverbération") is a numerical application of the Classical Theory of Reverberation as proposed by Sabine. It allows to obtain an evaluation of the diffuse sound field in a single room on the basis of Sabine's relations for the reverberation time and for the sound level of the reverberated field.

- Elements of validation
The TCR code was developed and is still maintained by the Acoustics team of Ifsttar (formerly LCPC), since 2007.
- ROOM ACOUSTICS: diffuse sound field evaluation in a single room
Advantages of the current version
- Instantaneous calculation of the diffuse field (reverberation time and sound level)
- Include direct field calculation
Limitations of the current version
- Based on the assumption of a diffuse field (Sabine's hypothesis)
- No coupled rooms
- No individual representation of first reflections (all contributions are included in the diffuse field)
