When exporting recordings from the Wireless units, such as the Wireless GO II, Interview PRO or Wireless PRO transmitters, in RØDE Central, it is important to understand the settings to ensure optimal output quality for its intended use.
Format
When deciding which audio format to use for exporting audio, it is essential to consider the specific requirements and purposes of the audio file. Both WAV (Waveform Audio File Format) and MP3 (MPEG-1 Audio Layer 3) have distinct characteristics that make them suitable for different scenarios.
- WAV files are uncompressed audio files, meaning they retain all the original audio data without any loss of quality.
- This format is commonly used in professional audio production, such as recording studios, due to its high fidelity and lossless nature.
- MP3 files are compressed audio files that reduce the file size by removing some audio data that may not be easily perceptible to the human ear.
- This format is widely used for online streaming, music distribution, and portable audio players due to its smaller file size and compatibility.
LUFS
One essential aspect to consider is choosing the appropriate Loudness or "LUFS" level. LUFS stands for Loudness Units Full Scale and refers to a standard measurement of audio loudness.
When selecting the LUFS level for your recordings, it's crucial to take into account the specific platform or medium where the audio will be heard.
- Many users prefer to keep this option turned off because they're able to adjust the loudness in other editing software.
- Different platforms have specific loudness requirements, and adhering to these standards can ensure that your audio is perceived correctly by the audience.
Bit Depth and Sample Rate
Another setting to consider when exporting recordings is the Bit Depth and Sample Rate.
- The Bit Depth of the audio file affects its dynamic range.
- If you don't need 32-bit float audio files for your project, we'd suggest using the 24-bit PCM option as the files sizes are smaller.
- To learn more about 24-bit and 32-bit floating-point formats, please refer to our article: Why can I export 24-bit files in 32-bit format using RØDE Central?
- Sample Rate defines the number of samples captured per second.
- In most cases, a Sample Rate of 48kHz is commonly used for audio projects, as it provides a good balance between audio quality and file size.
