Soundraw Artist Pro WAV and stems vs Sume Music at $0.125 a track

Soundraw gives stems and WAV only from its Artist Pro plan up, and its API only on Enterprise; Sume Music is self-serve, returns one audio file per generation at a fixed $0.125 and has no stem export. If you need to remix a track in a DAW, Soundraw fits; if you need a finished bed under video from an API, Sume does.

Soundraw facts are from its pricing page, read on 2026-10-02. Sume facts are from the Music 1.0 and Music Router docs.

What do Soundraw's plans include?

The page lists five plans (below) and says API access is included on Enterprise only; the four self-serve plans do not include it. Commercial use is permitted on each plan, with plan-specific royalty wording that this post does not summarize.

What does one Sume music call return?

One audio artifact per accepted generation, typically audio/mpeg, hosted on media.sume.com. The Music 1.0 docs describe no stem output and no WAV choice, so a track that must be split into drums and bass is not something Sume Music produces. Sume's own docs for audio joins say WAV is the sample-exact format for timeline audio, which only applies to files you pass through that route.

The price is a fixed $0.125 per accepted Music 1.0 generation, whether the prompt is 20 characters or 5,000 and whether an image is attached. Twenty tracks cost $2.50 and 100 cost $12.50, with no subscription. Soundraw's Artist Pro caps at 20 downloads a month for $35.99, or $23.39 on annual billing, so for pay-as-you-go use at low volume Sume is the cheaper way to get twenty tracks in a month, while a creator downloading hundreds of tracks may prefer an unlimited plan.

What does the monthly cost look like at different volumes?

Sume has no subscription, so the cost is linear. Soundraw's plans trade a monthly fee for download allowances, so the cheapest option depends on how many tracks you take. The table uses Soundraw's annual-billed monthly prices from the page; formats differ, so cost is not the only axis.

One more difference: Soundraw's page does not describe how a track is steered. On Sume you steer by rewriting the prompt and generating again, at another $0.125 per take. If your workflow is to browse, tweak and re-export one track many times, a plan with unlimited downloads suits that better than paying per generation.

How do I use a Sume track under a voiceover?

Put the track into a Timeline 1.0 soundtrack and set duck_db between 0 and 20 so the music dips under speech. Ducking needs a real spine, so it is rejected with duck_requires_audio_spine when the audio mode is silence. The soundtrack also takes gain_db and a fade_out_seconds of up to 10.

Which should I choose?

Pick Soundraw when stems, WAV and a library-style workflow matter and you can live with API access being an Enterprise conversation. Pick Sume when you want music generated through the same self-serve API, wallet and job system as your voice and video, and a single file per call is enough.
