Diffio-run comparison
22.5% greater average SCOREQ improvement in this measured cohort
On 100 matched 30-second Voices for Christ archival speech clips, benchmark version 0.3.0 measured Diffio 3.5 at 22.5% greater average SCOREQ improvement over the degraded originals than Adobe Podcast. SCOREQ is a model-predicted proxy score, not a human Mean Opinion Score, and this result applies only to this Diffio-run cohort. Review the methodology
Benchmark version 0.3.0
Average SCOREQ-predicted improvement versus the original
The comparison was assembled and run by Diffio on March 17, 2026. It compares the same 100 source clips processed by Adobe Podcast and Diffio 3.5. It did not include a human listening study, and it does not establish a universal quality winner. The matched audio and full distributions let you inspect the measured result directly.

Measured results
Model-predicted metrics across the 100 clips
Average model-predicted SCOREQ difference between Diffio 3.5 and Adobe Podcast across these 100 clips.
Clips where Diffio produced a lower ASR-based proxy WER than Adobe Podcast. This is not human intelligibility testing.
Clips where Diffio produced a higher DNSMOS OVR model prediction than Adobe Podcast.
Clips where Diffio had the higher SCOREQ model prediction; this is not a human preference count.
Diffio-run benchmark v0.3.0, generated March 17, 2026, with matched outputs and metric files on GitHub.
What this benchmark tests
This Diffio-run comparison uses 100 Voices for Christ archival sermon excerpts, each 30 seconds long (50 minutes total), with matched Original, Adobe Podcast, and Diffio 3.5 files. Benchmark version 0.3.0, dataset version 0.1.0; metric outputs were generated March 17, 2026.
How to read the metrics
SCOREQ and DNSMOS are model-predicted no-reference quality proxies, not human MOS. WER is an ASR-based review proxy: frozen large-v3 transcripts from the originals were compared with small.en decodes of the restored outputs. Lower WER is better, but it is not a human intelligibility measurement.

Why choose Diffio
Where Diffio goes beyond Adobe's published browser workflow
Adobe's Free and Premium plans center on its browser tools and daily Enhance Speech limits. Diffio centers on restoring compromised recorded speech through projects, source comparison, and a separately metered public API. Adobe Podcast plans
Compromised recorded speech
Use Diffio for focused restoration and denoising when speech is affected by noise, room echo or reverb, and supported distortion or clipping.
Project and source comparison
Keep the source and completed generation together in a project so you can compare the restoration in the web app before downloading it.
Paid video speech soundtracks
Paid plans can process the speech soundtrack of supported video files while the picture and other visuals remain unchanged.
Developer integrations
Use Diffio's separately metered public API when speech restoration needs to run inside an application or automated workflow.

Can Diffio handle old, noisy, or distant-mic audio better than Adobe Podcast?
Diffio is focused on compromised recorded speech, including noise and room echo or reverb. In this 100-clip Diffio-run comparison, Diffio 3.5 measured 22.5% greater average SCOREQ improvement over the originals than Adobe Podcast. SCOREQ is a model prediction, not a human listening score, so compare the matched clips and test representative material from your own workflow.
Do I need the Adobe ecosystem to use Diffio?
No. Diffio is a standalone web app and API; you can integrate it into any workflow without Creative Cloud or Adobe Express.
Is Diffio a good Adobe Podcast alternative?
Yes when you need focused speech restoration, a project and source-comparison workflow, or a public API. In this 100-clip Diffio-run comparison, Diffio 3.5 produced 22.5% greater average SCOREQ improvement over the originals than Adobe Podcast; the result is specific to this cohort.
Is Diffio an Adobe Enhance Speech alternative?
Yes. If you are evaluating Adobe's speech enhancer workflow, Diffio solves the same high-level problem of improving spoken audio, but this page focuses on compromised recorded speech.
Is the benchmark public?
Yes. Diffio assembled and ran benchmark version 0.3.0, then published the manifest, matched outputs, proxy transcripts, CSV results, and plot files on GitHub. It is a Diffio-run comparison, not an independent study.
What does MOS mean?
MOS means Mean Opinion Score, which ordinarily refers to human ratings. This comparison did not run a human listening study. SCOREQ and DNSMOS provide model-predicted proxies, while WER is an ASR-based review proxy against frozen transcripts.
