Who is the Compression (Production) poster for?
Compression (Production) belongs to the Music section rather than to a school year, because music is not something one grade owns. Anyone learning production can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Compression (Production) poster?
Set the ratio and threshold last. Get the attack and release right first — they are the sound. A wall chart earns its place by being glanceable from where the work is happening, so Compression (Production) belongs on the wall where that music work actually happens, within glancing distance, rather than filed away.
What other posters go with Compression (Production)?

Is the Compression (Production) poster free to download and print?
Yes. Compression (Production) downloads as a free PDF with no account, no email and no watermark, like everything else in the Music section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Compression (Production) poster print at?
Compression (Production) is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Compression (Production) loses nothing.Printing guide
