Here's Matt Vanacoro to show you how it's done in iZotope's powerful RX6 Audio Editor. RX6 Audio Editor from Izotope has been a saving grace for audio and video professionals everywhere. Nothing cleans out the hiss from a poorly grounded preamp or the rustle from a poorly placed lav mic like RX6. Jul 18, 2019 I’d rather deal with the selections that need de-clipping on an individual basis. In Logic Pro, I’ll open up the external editor with a key command (Shift+W by default, after you set iZotope RX to be your external editor). In Pro Tools, I’ll run the plug-in in my DAW, or use RX Connect.
IZotope RX's De-clip audio plug-in and module repairs digital and analog clipping artifacts. Audio clipping occurs when A/D converters are pushed too hard or magnetic tape is over-saturated. De-clip can be extremely useful for reducing distortion in recordings that were made in a single pass, such as live concerts, interviews, and any audio that cannot be re-recorded.

Resample allows you to convert an audio file from one sampling rate to another.
Sample Rate Conversion (SRC) is a necessary process when converting material from one sampling rate (such as studio-quality 96 kHz or 192 kHz) to another rate (such as 44.1 kHz for CD or 48 kHz for video).
It is common to record and edit in high sampling rates since higher rates allow higher frequencies to be represented. For example, a 192 kHz audio sample can represent frequencies up to 96 kHz whereas a 44.1 kHz audio sample can only represent frequencies up to 22.05 kHz. The highest frequency that can be represented accurately by a sampling rate is half of the sampling rate, and is known as the Nyquist frequency.
When reducing the sampling rate, or downsampling, it is crucial to remove the frequencies that cannot be represented at the lower sampling rate. Leaving frequencies above this point causes aliasing. Aliasing can be heard as the frequencies in an inaudible range are shifted into an audible range, causing distortion and noise. With iZotope SRC's steep low-pass filter, users can completely avoid the common aliasing artifacts while maintaining the maximum frequency content. A comparison of iZotope’s SRC process versus other sample rate convertors can be viewed at: http://src.infinitewave.ca/
You can also engage the Post-limiter option in order to limit the output levels of your signal to prevent any clipping from occurring.
Note: The Aliasing portion of the curve displayed in red shows the reflected frequencies during downsampling or imaged frequencies during upsampling — both due to aliasing. https://greatblack.weebly.com/blog/spectrasonics-omnisphere-2-keygen.
New sampling rate
This setting chooses the sampling rate you want to convert to. Choose a sampling rate from the drop-down list, or click on the field to type in a custom sampling rate.
Change tag only
Changes the declared sampling rate of the file in the file’s properties without resampling the file, effectively changing the playback rate and pitch of the file.
This feature is useful if the sampling rate tag was damaged by a previous audio editing process and the file is playing back incorrectly.
Filter steepness
This allows you to control the steepness of the SRC filter cutoff. The white line is representative of an ideal low-pass filter.
Higher filter steepness means better frequency performance of the filter: wider passband retains more useful signal, while stronger stopband attenuation provides better rejection of aliasing. At the same time, higher steepness of the frequency response requires a longer filter, which produces more ringing in time domain and energy smearing near the cutoff frequency.
Cutoff shift
SRC filter cutoff frequency shift (scaling multiplier).
Allows shifting the filter cutoff frequency up or down, to balance the width of a passband vs. amount of aliasing.
Pre-ringing
SRC filter pre-ringing amount in time domain (0 for minimum phase, 1 for linear phase, or anywhere in between).
Adjusts the phase response of the filter, which affects its time-domain ringing characteristic. The value of 0 produces a minimum-phase filter, which has no pre-ringing, but maximal post-ringing. Pc to mac software. The value of 1 produces a linear-phase filter with a symmetric impulse response: the amount of pre-ringing is equal to the amount of post-ringing. Intermediate values between 0 and 1 produce so-called intermediate-phase filters that balance pre- and post-ringing while maintaining linear-phase response across a possibly wider range of frequencies.
Post-limiter
Keeps true peak levels of the output signal below 0 dBTP to prevent any clipping from occurring.
This option is important when resampling signals that are very close to 0 dB, because filtering during resampling can change peak levels of a signal.

Batch processing audio can save you a huge amount of time and effort. Here's Matt Vanacoro to show you how it's done in iZotope's powerful RX6 Audio Editor.
RX6 Audio Editor from Izotope has been a saving grace for audio and video professionals everywhere. Nothing cleans out the hiss from a poorly grounded preamp or the rustle from a poorly placed lav mic like RX6. There are times, however, where running RX6 can be very time consuming, and as most of us may know, opening it up 3rd party audio plugins in Final Cut Pro is, well… less than fun. I often have a huge folder of video takes after a shoot that all need the same touch of RX6 love before I use them, and here’s how to process them all at once.
Step 1 - Get it Right the First Time
It’s not just one of my favorite Billy Joel songs, it’s the first step in the batch process! The first thing you’re going to have to do is open one of the files in RX6 and figure out exactly which modules you need to use, and nail down the settings for those modules. If you’ve got more than one module to use (like voice denoise followed by gain to raise the volume up) it may be easier to put them in a module chain to test out the order.
Now, you can adjust the settings in the batch process window later on, but for efficiency, I find it easier to simply save a preset for each module right now. This way I know the settings will be exactly the way I want them, and I don’t even have to open up the specific module’s window.
Step 2 - Line Up the Chain
Go to ‘Window’ and choose ‘Batch Processing’. This will open up the batch processing window for RX6. From here, you’ll want to first ‘add’ the files you plan on processing. RX6 will take audio files, but it will also take video files as well. It will extract the audio from the video file and give you a ‘bounced’ audio file as an output that matches your video file’s length exactly.
After you add your files, line up your ‘chain’ of processing steps. If you’re only using a single one, that’s cool too. It’s on this screen that you can use the drop down menu to select the preset you created for each module when you did your ‘test run’ in step one. If you didn’t save a preset, you can open the settings and tweak them now with the ‘view’ button. Just keep in mind you will need to ‘record’ the custom settings (the button right next to view) before the ‘process’ button in the bottom right will be activated for you.
Step 3 - Output Options
Now that you know what RX6 is going to do to your audio, it’s time to choose where that audio should go once it’s been processed. You can change the file format, choose a different folder, alter the file name. it’s all here. If you’re batch processing video, it helps to simply keep the same file name, this way if you sort by name every video file will have a corresponding ‘cleaned up’ audio file right next to it. Score!
Move Along
I can’t say enough how much faster processing audio is this way as opposed to trying to tinker with 3rd party plugins in your video editing app. You can even load up your favorite third party plugins to give it that ‘final polish’ before the video ever even hits your editor!
