(Program Loudness, Maximum True Peak Level, LRA - see They can be used to check compliance with Output file options, intros/outros, warnings, hardware settings, etc.)Īudio Processing Statistics of input and output filesĭisplay details about what our algorithms are changing in your files.

The Auphonic Leveler Batch Processor includes a Identify power line hum and all its partials.Īfterwards the partials are removed as necessary with sharp filters.Īn adaptive High Pass Filter cuts unnecessary and disturbing low frequencies,ĭepending on the context (speech, music or noise). In automatic mode, a classifier decides if and how much noise reduction Our Noise Reduction algorithms remove broadband background noise in audio files with slowly varying backgrounds.įirst the audio file is segmented in regions with different background noise characteristics, then a noise print is extracted in each region True peak level and ensures compliance with the selected loudness target. Is used to limit the final output signal to the selected maximum The loudness is calculated according to latest broadcast standards ( ITU-R BS.1770)Īnd Auphonic supports loudness targets for television ( EBU R128, ATSC A/85),Ī True Peak Limiter, with 4x oversampling to avoid intersample peaks, Processed files have the same average loudness. Global Loudness Normalization calculates the loudness of your audio andĪpplies a constant gain to reach a defined target level, so that all This algorithm was trained with over three years of audio files from our Web Service and keeps learning and adapting to new data every day. Most suitable for programs, where dialogs/speech is the most prominent content: podcasts, radio, broadcast, lecture and conference recordings, film and videos, screencasts etc.Background segments (noise, wind, breathing, silence etc.) won't be amplified.Music segments are processed with care: the overall loudness will be comparable to speech, but the natural dynamics are not changed as in speech segments.Loudness differences between speakers are corrected and dynamic range compression is applied.Music, background and speech segments are classified.Our Adaptive Leveler analyzes the content of audio files using machine learning techniques and is capable of balancing loudness variations between segments in one file: Bottom lineĪll in all, if you are looking for a straightforward software solution when it comes to normalizing your MP3 and WAV files to the same volume, you can give MP3 Normalizer a try and see what it can do for you.The following algorithms are included in the Auphonic Leveler Batch Processor: It doesn’t eat up a lot of CPU and memory, so the overall performance of the computer is not affected. Performanceĭuring our testing we have noticed that MP3 Normalizer carries out a task quickly. On the downside, there’s no support for other audio parameters that could help you adjust the audio channels, bit depth, and bitrate. MP3 Normalizer gives you the possibility to build up a list with the audio files that you want to process, remove the selected items from the list, overwrite the original files or pick the saving directory, as well as choose the desired percentage for normalizing the audio files. Additionally, you can view information about each file, such as filename, size, and location. You are welcomed by a well-organized set of functions that allows you to tweak the dedicated parameters with minimal effort.įiles can be added in the working environment using the built-in browse button, so you cannot make use of the drag-and-drop support. It proves to be particularly useful especially when you need to bring your audio files to the same volume and then burn them to a CD. MP3 Normalizer is a small software application whose purpose is to help you normalize MP3 and WAV files with the aid of batch processing operations.
