Acoustics products — one-time purchase
Editable spreadsheets and guides you own — pay once, keep forever, not a locked PDF.
RT60 Workbook
Reverberation time by octave band, current room versus proposed treatment, in a file you keep.
€9.95
An editable Sabine-equation RT60 workbook: up to 20 surfaces with your own materials and coverage, a proposed-treatment scenario, reference target ranges by use, and current-versus-proposed RT60 by octave band with a chart. It uses the same Sabine calculation as the free RT60 Calculator on this site. What the workbook adds is an offline file you keep and edit, your own absorption coefficients, and a before/after scenario.
- Sabine RT60 per octave band (125 Hz to 4 kHz): RT60 = 0.161 x V / A
- Up to 20 surfaces, each with its own material and coverage percentage
- Editable materials library: 14 generic materials supplied, 16 empty rows for your own manufacturer's coefficients
- Current room versus proposed treatment by band (up to 8 treatment rows, modelled as covering existing surface)
Acoustic Treatment Planner
Turn your room's numbers into a starting-point shopping list.
€4.95
Room size to a starting-point treatment plan: editable panel size and wall-coverage target, quantities by group (first-reflection panels, side-wall panels, rear-wall panels, corner bass traps, ceiling cloud) with where each goes, and a priority-ordered shopping list where you enter your own unit costs to get a total. No prices are built in.
- Wall area and volume from your dimensions
- Editable panel width and height and target wall coverage
- Quantities by group: first-reflection panels, side-wall panels, rear-wall panels, corner bass traps, ceiling cloud
- Where each group goes, with a rear-wall fit check and a ceiling-height check
Home Studio Acoustic Guide
A concise, illustrated introduction to planning your home studio acoustics.
€4.95
A 7-page illustrated PDF covering room modes, reflections, reverberation, speaker placement and a practical treatment sequence. A compact starting guide, not a personalized room report or workbook.
- Why small rooms sound problematic
- Room modes explained without the math-class tone
- Speaker Boundary Interference Response (SBIR)
- First reflections and the mirror trick
Studio Acoustic Toolkit
One room, entered once: modes, speaker placement, RT60 and a treatment plan in a single editable workbook, with the guides to use it.
€34.95
The flagship Studio Music Tools acoustic product. The Studio Project Workbook carries one room through room-mode analysis, a comparison of two speaker layouts, an RT60 estimate before and after treatment, and a treatment plan with your own costs, ending in a printable summary. Also included: the RT60 Workbook, the Acoustic Treatment Planner, the Home Studio Acoustic Guide, a Measurement Guide, a Studio Setup Checklist and a worked example. The free browser tools give quick answers; the Toolkit is the reusable planning file.
- Studio Project Workbook: enter the room once, and it flows through every sheet
- Room mode analysis with gap, coincident-axial and cluster flags (not limited to a fixed mode order)
- Speaker placement: Layout A versus Layout B, speaker-to-speaker and speaker-to-listener distances, first reflections, boundary cancellation (SBIR) table and practical checks
- RT60 before and after treatment by octave band, against a target range, with your own materials and up to 20 surfaces

Pricing FAQ
Is there a subscription or monthly plan?
No. Nothing on this site is a subscription. Calculators and Track Analyzer are free with no account. Mastering and stem separation are billed per use, once, when you choose to process a track. Credit packs (below) are a one-time purchase too — buying one never enrolls you in anything recurring.
How do credits work?
1 credit equals 1 standard profile mastering job — there's no confusing conversion rate to work out. Buy a pack once, spend credits whenever you master a track instead of paying €7.99 each time, and see your balance and full history any time on your account's Credits page. You can always pay directly instead. Reference mastering is a separate €2.99 direct payment and does not use credits.
What happens if mastering fails after I've paid?
If you paid with credits and the job fails on our end, the credit is refunded to your balance automatically — no request needed. If you paid directly via Mollie and a job fails on our end, contact us with your order number and we'll sort it out directly; direct payments aren't refunded automatically, so that path is handled by a real person rather than an unqualified “automatic refund” promise.
How long are my downloads available?
A paid order's download link works for a limited window after payment, shown on the order confirmation and your account's Downloads page — download your file within that window. Mastered files and separated stems both follow the same retention rules described in our Privacy policy.
What does “Preview” mean on Stem Splitter?
Stem Splitter works and can be bought, but it runs on infrastructure we're still validating at scale, so it is labelled Preview rather than fully live. You always hear a short free preview before paying, longer tracks can take several minutes to process, and if a paid job fails on our end you can contact us with your order number.
What audio formats and track lengths are supported?
WAV, MP3, AIFF, and FLAC are all accepted for upload. Analysis and mastering have different duration limits, shown on their upload pages. Current limits are shown on the upload pages; mastering eligibility is checked before payment.
More questions? See the full FAQ page.
Not sure where to start?
Track Analyzer and the acoustics calculators are free — start there before paying for anything.
