Digital tools that do real calculation, not decoration.
Every Studio Music Tools product is built from the same calculation engine used across this whole site — genuinely live, editable spreadsheets and original written guides, not static templates.

RT60 Workbook
Reverberation time by octave band, current room versus proposed treatment, in a file you keep.
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.
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.
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.
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
Free tools vs. paid products
Free, in your browser
The Room Mode Calculator, Speaker Placement Planner, and RT60 Calculator on /tools use the same calculation method as the paid workbooks, running live on this site. Free to use, no account, no time limit — this isn't a trial.
- Full calculation, not a limited preview
- No download, no offline copy — recalculates each time you visit
- No saved project: good for a quick check or comparing a couple of rooms
Paid products
An editable spreadsheet you keep, plus written guides and planning tools that aren't part of the free site at all.
- Yours to keep — edit, save, and reuse offline in Excel or Google Sheets
- The Toolkit carries one room through placement, RT60 and treatment, with a printable summary and your own cost planning
- One-time payment, not a subscription
