Measured traces and notes

Bring a measurement in#

1. 1

   Export it as text

   From your measurement software, export frequency and level per line, with phase if you have it: a REW text export, an .frd for SPL, a .zma for impedance, or a CSV.
2. 2

   Drop it on the tile it belongs to

   Drag the file onto SPL (dB), Impedance, Phase or Max SPL (dB). The tile says Drop to add a measured trace, and the tile decides what the numbers are: ohms on Impedance, decibels on SPL (dB). To paste a table instead, click the tile and paste.
3. 3

   Check what was read

   The trace draws at once, linked to the enclosure you have selected. A card at the foot of the dashboard says what was Added: the file, its range, how many points and whether phase came with it. Change the link there, open Details or Undo. The card goes after 12 seconds, unless something failed or the file could be read two ways, when it waits with Treat as.

Two more ways in: Add measured trace, at the foot of Measured traces under the enclosure list, and Export › Measured trace… in its Import part. Both take several files at once. If the tile for a trace’s kind is not on the dashboard, it is added.

What it reads#

• Only lines that start with a number are read. Each is a frequency, a value and, optionally, phase in degrees, separated by spaces, tabs, commas or semicolons. Everything else is kept as the file’s header.
• A file added with Add measured trace or from the Export menu has no tile to go by, so unless it is a .zma or .frd its kind is guessed from the numbers. Whenever a file could be read two ways, the card asks with Treat as; a table of decibels with 64 rows or fewer is offered as Max SPL too.
• It needs at least 5 rows. A sweep with about 48 points per octave or more is stored on a 48-per-octave grid and drawn as a line; anything sparser, or 64 rows or fewer, is kept as it is and drawn as points.
• The header is read for the measuring software (REW, ARTA, CLIO, DATS, VituixCAD, Klippel, OmniMic), the date and any smoothing it already applied.
• A workspace holds up to 24 traces.

Link it and line it up#

Click a trace in Measured traces, or its pill in a graph’s legend, to open its details.

How a trace is drawn#

• The eye on a trace’s row hides it everywhere. The eye on its legend pill hides it on that graph only.
• Each pill shows the trace’s badge (M1, M2…), its name, its offset when it has one, and its value at the cursor, so you can read it against the simulated curves.
• Measured conditions, all optional: Distance, Space (Half space, Full space, Quarter space, Eighth space or Ground plane), Drive, Mic, Date and Notes. Fill them in when you share a design, so others know how it was measured. The date comes from the file when it says.

Graph notes#

A graph note points something out on a graph, for you later or for whoever you share the design with. It is saved with the workspace, published with its shares and kept when someone makes a copy.

1. 1

   Add one

   Right-click a graph and choose Add note: a point on an enclosure’s curve, a line at that frequency, a band around it or a level. Or click the graph to hold the readout and press Note here. On a phone, tap the graph, then Note here.
2. 2

   Write it

   Label on the graph is the short label drawn on the chart, up to 48 characters. Say more (optional) takes up to 280. Switch between Point, Line, Band and Level, type exact frequencies, and pick the enclosure a point rides on or a mark takes its colour from.
3. 3

   Keep it

   Done closes the note; a note closed with nothing written in it is removed, and Esc puts it back as it was. Click its label on the graph to edit it again, with Delete, Delete all and Copy link at the foot.

• Up to 6 notes on one graph and 30 in a workspace.
• Headroom, Compare, Metrics, Insights, Schematic, Horn Editor, Fold, Baffle Layout and T/S Parameters take no notes; the other graphs all do.
• Someone opening your shared design clicks a note’s label to read it and copy a link to it.

Show or hide annotations#

Beside Undo and Redo, a button (Hide annotations, then Show annotations) hides your notes and your assistant’s marks together, and brings them back. It only appears when there is something to hide, and adding a note turns annotations back on.

Your assistant’s marks are the numbered bands, lines, levels and points it draws while it explains a design through the 00 Simulator connector (annotate_graphs). They sit on the graphs in the tab you have open, never change the design, and clear themselves once the design changes. Watch it work live has more.
