I remember how eager I was to get into music production. The arrangement possibilities were endless, and I could learn how to make mixes sound like what I heard. Unfortunately, in the chaos of beginning to produce, I didn’t learn the basics of how a computer actually handles audio, so the whole concept of making music on a laptop felt a bit abstract.
Even bouncing my first track was confusing. What does each of the options do? How was I supposed to know what would sound best?
In this article, we’ll cover some basic aspects of digital audio, and how they affect the production process. Today, we’ll focus on sample rate and bit depth, as well as a few topics related to them. It’s a bit of theory and a bit of math, but hopefully it will peel away some of the mystery behind how digital audio works.
IZotope’s RX is best known for its audio repair and enhancement capabilities, adored by the largest broadcast and post-production facilities across the globe. That said, RX 7, the latest version of the toolkit, also boasts various features that make it a powerful asset for. Only at Sweetwater! Instant Delivery for your iZotope Music Production Suite 3 Upgrade from Music Production Suite 1 or 2!

Bit depth doesn't matter as much as the algorithm design. Sound Forge 10 and RX Advanced are using a 64-bit iZotope algorithm. Audition uses its own algorithm, it is pretty good too, don't know what the bit depth is. How to Use Music Rebalance in RX 7 Sep 13, 2018. Isolate mix elements from a single track with the new source separation module in RX 7, Music Rebalance. Easily reduce vocals in background music for clearer dialogue, learn how to remove vocals from a song, or separate vocal stems from a track for easy remixing.
What is “digital audio” in the first place?
Digital audio is the system in which we store, recreate, and manipulate audio information in a computer system. Certain characteristics of an analog sound wave, like the frequency and amplitude, are converted to data computer software can read. This allows us to manage, edit, and arrange audio in a software-based context.
The sound wave is converted into data through a series of snapshot measurements, or samples. A sample is taken at a particular time in the audio wave, recording amplitude. This information is then converted into digestible, binary data.
Batch Processing allows you to automate processing on groups of files, or apply processing from multiple modules to files. This can save hours when repairing files that require the same processing, or even something as simple as converting audio files to the same format, sample rate, etc. RX 7 Overview. IZotope’s award-winning RX Audio Editor is the industry standard for audio repair, restoration, and enhancement. The following options are available when exporting files to this file format: Bit Depth: Determines the bit depth of the. If you are not able to hear the audio sent to RX from your DAW with RX Connect, change.
The system makes thousands of measurements per second. If we can take tons of measurements extremely quickly with enough possible amplitude values, we can effectively use these snapshots to reconstruct the resolution and complexity of an analog wave.
Export Selection
This option will allow you to export only the audio that is contained within your current selection as opposed to the entire audio file.
When exporting, you will be able to define the output file name, directory, and bit-depth.
Export Screenshot
RX allows you to export your current spectrogram/waveform display as a PNG image file. This can be very helpful for archiving any restoration process or forensic documentation.
When clicking on 'Export Screenshot' from the 'File' menu, your current spectrogram/waveform view will be used for adjusting your screenshot size and position.
