Everything worth knowing about a room's sound.

The guides, standards, comparisons and plain-English explainers behind Echo — in one place, so you can go as deep as you want before you check a room, or after.

Studio and Pro

Five working tools, included with Echo Studio

These tools work with your own rooms and numbers. Try each one with a worked example first. Echo Studio is £149 a month, with a 3-month minimum and then cancel any time. AV coverage, the noise budget and NC/NR rating are included in Echo Studio and Echo Pro. Without a subscription they are £29 a project each. The Decision Pack (£69 a room) and the Acoustic Brief Builder (£75 per room type) are sold separately and are not part of Studio or Pro. Ordering for these opens soon.
