Editing your voice-over clips may be much simpler with the correct audio workstation. Even if Linux doesn't have all the same programmes that are frequently suggested for Windows and macOS users, there are still a tonne of fantastic and suitable tools you may utilise to produce flawless work.
The top Linux voice-over programmes are listed below.
1. Audacity

An outstanding digital audio workstation (DAW) in every way is Audacity. Because it's well-documented, cost-free to use, and offers a vast array of potent capabilities, it's one of the most often utilised software among voice-over artists.
If you've never edited audio before, Audacity is one of the greatest programmes to use as a starting point. You may typically find solutions to any problems you encounter by Googling online or asking knowledgeable users on a forum because so many people like using Audacity. Audacity may also be used to edit podcasts, make ringtones, and record music.
Audacity has a few characteristics that set it apart from other DAWs. If performance is a concern, you may like how Audacity is both strong and light. Due of Audacity's compatibility with the majority of audio file formats, it is also incredibly adaptable.
Audacity does have certain shortcomings. Compared to many other audio workstations, its UI is far more crowded. If this is a problem, you can resolve it by changing the settings in View > Toolbars, but it's also worthwhile to take into account programmes with a simpler interface.
2. REAPER

One of the most capable programmes voice actors may use to edit their work is REAPER. Both novices and experts will find the application's capabilities to be useful. It is well renowned for integrating significant time-saving capabilities with an intuitive user interface.
All the essential components of digital audio workstations are included in REAPER, including spectrum editing, a wide range of practical effects, and basic clipping and editing capabilities.
Action commands are likewise included in REAPER. These instructions are highly well-known because they let users associate a number of operations with keyboard shortcuts. If you make action instructions for any repetitious tasks you come across, you'll soon discover that you can do difficult editing with the touch of a single key.
If you're thinking about using REAPER, bear in mind that you will have to pay for the privilege. Users of REAPER who earn less than $20,000 annually can acquire the non-commercial licence for $60, while those who earn more are required to pay $225. A 60-day trial period is available for you to decide if REAPER is the correct choice.
3. Spek

There is no more effective programme to employ than Spek if you're interested in thoroughly analysing your audio files. The majority of audio file formats are compatible with this compact spectrum analyzer. For artists who are ready to learn how to utilise it, it has an obvious benefit over waveforms: it charts sound frequency.
You may utilise Spek to spot problems in your performance like sibilance (uncomfortably loud "S" noises). By keeping an eye on the frequencies in Spek, you may experiment with your setup and mouth motions to resolve audio problems, or you can utilise the application's output as a guide throughout the editing process.
Spectrum analysis is difficult to learn, and for many voice-over actors, it takes months or years of practise before it becomes second nature. It's valuable since it enables you to analyse your work with both your ears and your eyes. Spectrum analysis can identify and fix a lot of audio problems in a matter of seconds.
Spectrum analysis tools are included into certain digital audio workstations, but not all of them. There is no more capable and user-friendly solution than Spek if you require a separate spectrum analysis tool. You won't regret installing the programme because it is totally free to use.
4. Traverso DAW

A sophisticated multitrack recording and editing platform, Traverso is a condensed digital audio workstation. Because Traverso forgoes a complicated user interface in favour of easy navigation and well arranged audio monitoring options, a lot of people adore using it.
The programme contains capabilities for basic editing and cutting as well as requirements like audio filters. Additionally, it includes a strong history feature that gives you many more undo and redo options than other programmes provide. Traverso is well renowned for being very light and functioning on the majority of operating systems.
If you want an application that has all the requirements without any unnecessary fluff, you should think about utilising Traverso.
Traverso has a special attraction for novices since it concentrates on the most crucial elements and fosters a concentrated learning environment, unlike rival programmes that include some functions that are necessities for seasoned artists.
5. Ocenaudio

Ocenaudio is a free audio workstation that has attracted a devoted following due to its uncomplicated user interface and comprehensive feature set. Even while ocenaudio and Audacity are quite similar, ocenaudio purposefully has a more pleasing interface and better performance.
The outstanding preview function of ocenaudio is one of its enticing features. You may configure and apply new effects while listening to audio previews at the same time. It's a great tool to use for audio analysis and fine-tuned noise removal.
Ocenaudio has its own distinct set of problems, much as other DAWs. The absence of documentation is ocenaudio's main problem. Many aficionados have created YouTube videos and blog entries in recent years that offer greater explanations of how to use the programme.
6. Ardour

Professional DAW Ardour. It is designed for audio engineers who desire to utilise a robust open-source editing programme. You may record, edit, and master your voice-over projects using Ardour's comprehensive set of capabilities.
There are a few aspects of this programme that make voiceover work intriguing. Beginners and those on a tight budget may appreciate that Ardour is cost-free. Ardour is also one of the most potent apps you may employ when compared to many other DAWs.
A lot of online documentation is available for Ardour, and its user interface is nice. Even though it isn't as well-known as many other voice-over programmes, many experienced users prefer it, so you shouldn't have any trouble getting support if you need it.
The primary problem with Ardour is how scary it can be for beginners. You'll need to explore with Ardour as you learn how to use it because it has many features targeted at professional audio engineers and musicians, and a lot of the vocabulary is also industry-specific.
Consider Using Wine to Run Essential Software
There is no shortage of fantastic software on Flatpak and online, but occasionally using a particular programme is required to achieve the desired result.
If the voice-over programmes offered by Linux don't meet your needs, you should think about utilising Wine to run a Windows-compatible voice-over programme.
