iZotope RX Audio Editor

iZotope RX is an advanced set of tools that enable you to repair and enhance sound quality or audio issues, such as noise, distortions, crackle and faulty recordings. The software offers professional tools for repairing audio tracks and streams from media files, without effort. The powerful audio manipulation tools reduce user interference.

Precision audio editing

iZotope RX allows you to manipulate audio streams like a professional editor, with high accuracy, thanks to the multiple options offered. The application allows you to apply declipping filters, as well as declicking, remove humming, audio noise or repair the audio specter. You may adjust the audio gain, equalizer, channels, resampling rates and the dithering.
These modules allow you to manually adjust the levels and compare the result with the input file. Additionally, you may opt for selecting presets, which automate the sound editing, by applying pre-made adjustments. For instance, when selecting the Declip module, you may choose between digital clipping, analog clipping, high quality clipping, at -1dB, as well as mild and subtle clipping. Similarly, with the Declick option, you can easily fix discontinuous waveform, remove GSM cellphone buzz, thumps, short digital clicks or vinyl record crackles.

Sound quality for post-production editing

iZotope RX is a professional application that enables you to manipulate the sound from one or several audio tracks at the same time, as well as copy, cut and paste pieces from one stream onto another. Moreover, the software allows you to perform a precise pitch adjustment, with the help of the hum removing tool or the denoising option. The Denoise module allows you to view the track as noise profile, residual noise and curve lines, that you can individually modify.
The Spectral repair tool allows you to attenuate the strength and direction of the sound, while the audio gain option allows you to create fade in/out effects, using the log, linear, cosine or equal power algorithms. Similarly, the re-sampling tool allows you to adjust the filter steepness and the aliasing.

Powerful tools, modules and plugins

iZotope RX can display the loaded track as a duplicate waveform, representing the input stream and the result, so you can easily compare them after applying the modifications. You may enable the loop playback and make the adjustments as the audio file is playing. Additionally, iZotope RX can be connected to the audio/video editing program of your choice, in order for you to edit the feed received from the editor.
