![]() If you prefer to handle this in real time (on-line), refer to my article “Podcast Loudness Processing Workflow. I demonstrate a sort of manual “off-line” Loudness Normalization process. If you are finding it difficult to achieve acceptable results, I suggest you apply the concepts described in this video tutorial that I produced. Also, make sure the input file has sufficient headroom, with existing True Peaks well below 0dBFS. ![]() If you are going to use these processing options, my suggestion would be to make sure the measured Program Loudness of your input file is reasonably close to the Program Loudness that you are targeting. Hit F2, or click on Effects-Amplitude & Compression-Normalize (process), and. [– If a Match Volume process (Match To/ITU-R BS.1770-2 Loudness) yields a compliant True Peak Ceiling right out of the box, there is no need to run any subsequent processing. The next step is to normalize your recording. [– If the Match Volume Processor (Match To/ITU-R BS.1770-2 Loudness) applies limiting that results in a Peak Ceiling close to full scale, any subsequent limiting (Match To/True Peak Amplitude) has the potential to reduce the existing Program Loudness. For Program Loudness and True Peak compliance, it may be necessary to run both processing stages sequentially. This is essentially a True Peak Limiter that is independent of the ITU Loudness Processor. Adobe Audition.You can also use a playlist or soundtrack to group multiple audio files together and display them on your website in an organized manner. The Audition Match Volume Processor also features a Match To/True Peak Amplitude option with a user defined True Peak Ceiling (referred to as Peak Volume). This will result in insufficient headroom for both True Peak compliance and preparation for MP3 encoding. My tests revelaled Peak Ceilings as high as -0.1dBFS. The ITU Loudness processing option does supply a basic Limiting option. Any time a gain increase is applied, you run the risk of pushing the Peak Ceiling to elevated levels. ![]() And so depending on various aspects of the input file, it’s possible the processed audio may not comply due to an unsuitable Peak Ceiling.įor example if you need to target -16.0 LUFS Program Loudness for internet/mobile distribution, the Match Volume Processor may need to increase gain in order to meet this target. The problem with this option is the Processor will not allow the operator to define a True Peak Ceiling. It is also possible to customize Loudness Normalization Tolerence.Īdobe Audition CC has a handy Match Volume Processor with various options including Match To/ITU-R BS.1770-2 Loudness. To quickly select, reposition, or delete multiple keyframes, see Adjust automation with keyframes. In the Waveform Editor panel, click the yellow envelope line to add keyframes, and drag them up or down to change amplitude. It is now possible to define a True Peak Maximum, as well as Integrated/Program Loudness targets. To boost or reduce amplitude over time, choose Gain Envelope ( Effects > Amplitude and Compression ). The current version of Adobe Audition CC has been greatly enhanced, specifically in regards to the Match Loudness Module. *** UPDATE: Please note this post was written in 2014.
