Audacity
Audacity is the most widely used free audio editing software in the world — the open-source desktop application that has been the default starting point for podcast audio editing since podcasting began. For solopreneurs who want complete control over their audio editing without any subscription cost, Audacity provides professional-grade audio processing tools including multi-track editing, noise reduction, normalisation, equalisation, compression and hundreds of VST plugin effects. The noise reduction tool is Audacity’s most practically valuable feature for podcasters. Record a few seconds of room noise before the episode begins, use that recording as the noise profile and apply noise reduction to the entire recording — the tool filters out consistent background noise (air conditioning, computer fans, room hum) that would otherwise degrade recording quality. For solopreneurs recording in home offices or non-professional environments without acoustic treatment, noise reduction significantly improves the professional sound of the final audio. Normalisation and compression tools adjust volume levels across the entire recording — ensuring consistent loudness that meets the −16 LUFS stereo target that Spotify and Apple Podcasts recommend for podcast audio. Manual equalisation allows boosting or reducing specific frequency ranges to improve vocal clarity. The multi-track editor handles separate audio tracks for host and guests, intro/outro music and sound effects. Audacity’s plugin ecosystem includes hundreds of VST effects that extend the base functionality: de-essers to reduce harsh ‘s’ sounds, noise gates to silence background noise between speech, and audio restoration tools for improving poorly recorded audio. Export to MP3, WAV, FLAC and other formats with configurable quality settings. Cost: completely free. Available for Windows, macOS and Linux.

- Open-source project — customer support relies on community forums rather than dedicated team
Audacity Review 2026 — The Best Free Podcast Audio Editor
Audacity is the podcast editing software that every solopreneur should know about — not because it is the most modern or the most AI-powered option, but because it is completely free, professionally capable and has been the trusted audio editing foundation for independent podcasters for over two decades. For solopreneurs who want professional audio editing without a subscription cost and are willing to invest time learning the interface, Audacity delivers every technical capability needed for high-quality podcast production.
Why Free Matters in Audio Editing
The paid podcast audio editing landscape includes tools at $24-40+/month. For a solopreneur in the early stages of podcast production, before audience and revenue have been established, a $300-480/year editing software subscription is a significant cost commitment relative to the current business value of the podcast.Audacity’s zero cost removes this barrier entirely. The editing capability is professional-grade — the same multi-track editing, noise reduction, normalisation and compression that paid tools provide, without a subscription. For solopreneurs who are willing to invest time learning the interface rather than money on a subscription, Audacity is the rational starting point.
Noise Reduction — The Essential Podcaster Feature
The noise reduction tool is Audacity’s most commercially valuable feature for home-recording solopreneurs. Record three to five seconds of room noise at the start of each session, use that sample as the noise profile and apply noise reduction — Audacity filters out the consistent background noise pattern across the entire recording, removing air conditioning hum, computer fan noise and room ambience that would otherwise make the recording sound amateurish.This noise reduction capability alone justifies learning Audacity for any solopreneur recording in a home office, spare room or other non-professional acoustic environment.
Professional Audio Processing Suite
Beyond noise reduction, Audacity’s processing tools cover the complete podcast audio preparation workflow: normalisation to -16 LUFS for platform compatibility, equalisation to improve vocal clarity, compression to even out volume variations, and multi-track mixing for combining host audio, guest audio, intro/outro music and sound effects into a finished episode.
Our Verdict
Audacity is the right starting audio editor for solopreneurs who want professional podcast production capability at zero cost. Learn Audacity first, then evaluate whether the time savings of AI-powered tools like Descript justify upgrading to a paid subscription when production volume and business revenue support the investment.
