Office de Radiodiffusion Télévision Française (ORTF) was a French public broadcasting organization established in 1964. ORTF consolidated four pre-existing entities: Radiodiffusion-Télévision Française (RTF), Office de Radiodiffusion-Télévision Française d’Outre-Mer (ORTFOM), Société Nationale de Télévision Française 1 (SNTF1), and Télédiffusion de France (TDF). ORTF had a monopoly on radio and television broadcasting in France and its overseas territories.
The O-R-T-F Method: An Ideal Microphone Placement for Various Situations
The O-R-T-F (omni-directional-right-top-front) microphone placement technique offers a versatile and immersive audio experience. It involves using four microphones arranged in a specific configuration to capture spatial information accurately.
Microphone Arrangement
The O-R-T-F setup consists of:
- Omni microphone (O): Placed at the center, it captures the overall ambient sound.
- Right microphone (R): Positioned 17 cm to the right of the center, facing forward.
- Top microphone (T): Placed 17 cm above the center, pointed down towards the sound source.
- Front microphone (F): Located 17 cm in front of the center, angled upwards at 110 degrees.
Advantages
- Spatially accurate: The O-R-T-F technique captures sound from different perspectives, resulting in a realistic and immersive auditory experience.
- Stereo compatibility: The placement of the R and L microphones ensures compatibility with stereo playback.
- Consistency: The standardized setup maintains consistency across different recording environments and setups.
- Control over soundstage: The adjustable spacing and angle of the microphones allows for fine-tuning the width, depth, and stereo separation of the sound.
Applications
The O-R-T-F method is ideal for various recording scenarios:
- Music: Studio and live recordings, capturing the full ambiance and instrument separation.
- Film and video: Creating immersive soundtracks with authentic spatial cues.
- Podcasts: Enhancing the dialogue and natural sound environment.
- Audiovisual presentations: Delivering engaging and spatially accurate audio experiences.
Additional Considerations
- Microphone spacing: Maintaining the recommended 17 cm spacing is crucial for optimal results.
- Microphone quality: Use high-quality microphones with wide frequency response and low noise levels.
- Room acoustics: The recording environment should have minimal reflections and reverberation to avoid unwanted coloration.
| Microphone | Position Relative to Center | Angle (if applicable) |
