You no longer need a full recording studio with padded walls and expensive mics to create good-quality audio. A laptop, a quiet place, a decent mic and some of the best audio editing software will produce a result that, while not perfect, will get the job done at a fraction of the cost and still deliver extremely high quality audio.

That said, it’s possible to spend hundreds of dollars on audio editing software, but there are free alternatives too - it’s a market that supports a variety of entry points, and it’s important to choose the right one for you so you don’t end up paying over the odds, but equally don’t end up saddled with software that doesn’t support the features you need. Some packages are aimed at musicians, others at single voices, or a small number of speakers. Getting the right one for you is a large step in the direction of producing an excellent final result.

Some of the software here is more suitable for beginners. If you’re just starting out in the world of audio editing, it can make sense to use a free app so that your financial loss isn’t too great in the event that you don’t go on to make a career out of it. It's also a good way to learn the basics. Signing up for a subscription to one of the more expensive packages can net you a lot of advanced tools, but getting the basics of recording and editing right counts for more in the long run than clever tricks.

Consumer-grade hardware has been able to handle digital audio editing for 30 years or more, but modern fast processors and storage, coupled with operating systems that make things easy rather than obscure text-based interfaces, mean that today recording and editing your podcasts and narration tracks is easier than ever. Cutting and mixing tools have advanced since the days of quarter-inch tape and a razor blade, and it’s now possible to keep a full audio editing suite on your hard drive.

The only real issue is that you may need a newer home computer or laptop to really get the most out of some audio editing apps. And if you want to merge your audio with footage, you should also check out specialized video editing software.

Adobe Audition is one of the most user-friendly audio editing programs available. You can customize the layout to accommodate your workflow, and the software has all the best tools for editing and finalizing any audio project.

This allows you to record multiple sources simultaneously on separate tracks. This makes post-production tasks like editing and effects processing easier. All that makes it ideal for podcasters, vloggers and anyone straddling the amateur/professional divide.

Audition’s audio restoration tools make it easy to fix damaged or old recordings. This is super simple to use, as you highlight he offending sounds, hit a button and Audition takes care of removing that from the rest of the audio. Audition doesn’t negatively affect the source material when it restores poorly recorded audio either – a big plus.

To use the program, you pay for a monthly, yearly or multi year subscription. It also comes packaged with Adobe’s Creative Cloud subscription, which is a better deal if you plan to also edit photos or videos. Adobe offers discounts to students and teachers as well as businesses that need multiple licenses.

Audacity

A free audio editor that has some great tools

Wide OS compatibility
Great voice recording tools
No support options besides its user forum
Destructive editing isn't for everyone

Audacity is free, open source audio editing and recording software with an impressive list of editing and restoration tools. The interface isn’t the most attractive, but it is easy to use.

Audacity’s noise-reduction plugin is a one-click solution for removing unwanted room noise. An impressive tool for a free piece of software. The click-removal tool also worked well, but it can drastically alter the source material and make it sound worse, so use it with caution. Luckily, Audacity allows you to preview the edit to adjust the settings before making any destructive changes.

This program works on Macs and PCs and is a light load for your computer. It’s compatible with most of the important audio file types, including MP3 and lossless formats like WAV, AIFF and FLAC. Audacity imported our 1.5-hour podcast test segment in less than five seconds, which was faster than most of the for-pay programs we tested.

As such you can play with audio in a non-destructive way. This is great for lining up an album full of tracks ready for mastering, for example. 

A Windows only platform that justifies its higher-end price tag with lots of powerful features which make it ideal for professional musicians.

Avid Pro Tools is a truly professional audio editor that's used in studios all over the world as the go-to system of choice for music producers, film editors and beyond. As such it's made to work well with physical controls, isn't easy to pick-up for beginners and costs a tidy sum.

But all that's part of what makes this a very powerful tool. This DAW offers video specific features like 4K, 120fps support, Dolby Atmos editing and even Netflix Post Technology. Beyond video you have the ability to work with 1,024 MIDI tracks, 512 instrument tracks and 128 auxiliary tracks. 

Stand out tools like Clip Gain, to quickly adjust volumes; and Beat Detective, to fix timing issues easily, are just a few of the powerful features this audio editing suite offers to justify its price.

Apple Logic Pro X 10.5

Best for pro Mac users

Full DAW: No | Aimed at: Pros | Pricing: Affordable higher-end

Auto sampler
Super stop sequencer
Drum synth is incredible
Some third-party plugin issues
Four mod matrix limit in quick sampler

Apple Logic Pro X 10.5 is a professional grade audio editor that incorporates some of the best features into an interface that's super intuitive and supportive of a fast workflow. Yes, this isn't for newbs, but it certainly does make the complex world of audio editing seem less daunting. For professionals it just makes life easier.

The software does all this by offering all the features you'd expect but also a clever system of grid-based clip launching. These "cells" allow you to compose and arrange music in real-time, making this ideal for broadcasting or live music events. Other features like the Remix FX plugin, Step Sequencer, and Quick Sampler all help to further speed up and automate the working process. 

In a typical Apple fashion this takes a tool we already have and makes it more minimalist and therefore easier to use. It also does this while undercutting the big names in the business on price.

In addition to the editing window, there is a file browser, an effects chain and a waveform analyzer you can add or remove as you need.

Acoustica’s tools created some of the best results in our audio restoration test.


Important Features to Consider 

Tracks
The number of tracks your editing software supports limits how many audio streams you can edit together at once. Many albums have been recorded on four-track recorders, but you don’t need to limit yourself by that. It’s possible to merge tracks down, freeing up one by combining two, or you can just let rip with as many tracks as your software supports and your hardware can manage. Many of the apps we’ve tested here can only record two tracks per session, meaning you’ll need to edit multiple recording sessions together if you need more.

Recording
Some software is dedicated to editing, requiring you to record elsewhere and import your audio files, while other apps can handle the recording process too. Some can record from multiple sources at the same time, which is known as multitrack recording and useful if you’re organizing a round-table podcast in which everyone has their own mic.

Editing
Simple editing tasks like fades, cuts, volume normalization (making all your tracks the same loudness), and the copying and pasting of sections come as standard. Additional features are more specific to the app in question. The very best software lets you play with effects such as echoes and pitch-shifts, and may have mastering output options to make sure you hit industry-standard volume levels ready for digital distribution or even turning into CDs.

How much should you spend on Audio Editors?

The only reason to spend more than $100 on editing software is if you plan to compose music with virtual instruments, produce complex arrangements or mix and master recordings professionally. 

We recommend $200 as the right price for music production software, and $500 or more if you are recording and finalizing projects in a professional capacity. The programs we tested for this comparison are the perfect solution for recording podcasts, editing and repairing field recordings and digitizing an old vinyl collection.
