Adobe Podcast Enhance Speech is a free browser-based AI tool that removes background noise and echo from any audio recording — transforming a noisy home recording into something approaching studio quality. Upload, click enhance, download. Free for files under 30 minutes. No software required.
Adobe Podcast is a browser-based audio tool from Adobe with one standout feature: Enhance Speech. Upload any audio recording and Adobe's AI removes background noise, echo and room reverb — transforming a recording made in a noisy environment or on a laptop microphone into something that sounds close to studio quality. No software to install, no technical settings to configure. Upload, click enhance, download.
Enhance Speech is free for audio files under 30 minutes. This makes it the most accessible professional audio cleanup tool available — any podcaster, interviewer or content creator can process their recordings for free in under 10 minutes per file. The limitation is that it is a single-purpose tool: it cleans audio. It does not edit, transcribe, structure or publish.
Adobe Podcast also includes Mic Check (analyses your microphone setup before recording) and a browser-based recording studio, but Enhance Speech is the feature most users know it for and the reason most visit the site.
It does: remove consistent background noise (hum, HVAC, traffic), reduce echo and room reverb, improve voice clarity and presence, and make recordings sound more balanced.
It does not: remove intermittent sounds (a dog barking once, a chair scraping), fix distortion or clipping from recording too loud, work on music, or edit the audio in any way. It is a cleanup tool, not an editor.
The V2 update received mixed feedback — some users report the enhanced audio sounds slightly processed or artificial compared to V1. Independent testing suggests it is still significantly better than unenhanced audio for noisy recordings, but users who record in good environments may prefer the original. Always compare the enhanced and unenhanced versions before using.
Podcasters who record in imperfect environments (home office, noisy rooms) and need a quick cleanup step before editing. Content creators who record with built-in microphones. Journalists and researchers processing recorded interviews. Anyone who has a recording that sounds rough and needs a fast, free improvement before using it.
If you want to edit the audio after cleaning it, you need a separate tool — Descript for transcript-based editing, Audacity or Adobe Audition for traditional waveform editing.
Go to podcast.adobe.com/enhance. No account required for basic use. Click Upload audio, select your file (MP3, WAV, AAC, FLAC, OGG, M4A — under 500MB and under 30 minutes for free). Click Enhance. Wait up to 10 minutes for processing. Play the enhanced and original versions side by side. Download the enhanced WAV file.
Always keep the original file. Enhance Speech V2 occasionally produces audio that sounds slightly artificial on already-clean recordings. Always keep your original untouched. If the enhancement does not improve the audio, use the original.
Free tier is genuinely sufficient for most use cases. Files under 30 minutes, processed one at a time, at no cost. Most podcast episodes and recorded interviews fall under 30 minutes after editing. The free tier covers the primary use case without needing to upgrade.
Adobe Podcast Enhance Speech uses AI to separate the speech signal from background noise using spectral subtraction and neural audio processing. Per Adobe's official product page, it processes audio files under 500MB and returns an enhanced WAV file, typically within 10 minutes. The free tier handles files under 30 minutes. Adobe Express Premium ($9.99/month) unlocks files up to 2 hours and batch processing.
Enhance Speech is part of the broader Adobe Podcast suite, which also includes browser-based recording and transcript-based editing. The suite is accessible at podcast.adobe.com and is separate from Creative Cloud, though Creative Cloud subscribers may have access depending on their plan.
