Practice Made for Your Voice
Warm-ups cut to your range, lessons you sing along to, and your pitch drawn live as you sing. Free on iPhone, Android and the web.
Free. Not a trial. No card needed.



See Every Note You Sing
Your voice is drawn over the guide notes as you sing, as The Line or The Drop. After each exercise, a score card shows how much was in tune and marks every note held, close or off.
A Session Made for Your Voice
A warm-up, something to work on and a cool-down, cut to your range. Five, 10 or 20 minutes, whatever the day allows. Free.

Lessons You Sing, Not Just Read
75 lessons in 15 units, with moving drawings, breath timers, sing-alongs and held-note checks. The 25 Foundations lessons are free.
Remember Everything Your Teacher Said
Upload a lesson recording and get it back in chapters: your teacher’s cues, your tries to replay, homework and a play-along at three-quarter speed. Your first lesson gets full notes, free.

84 Exercises. All in Your Key.
40 of them free, plus ready-made routines for when you don’t want to choose. Pro lets you set your own key range, direction and step size.
Sing Through a Straw. Feel It Get Easier.
Straw work runs through the free Foundations lessons, and the guides for every Resono are free in Rayvox Studio.

Questions About Studio
Is Rayvox Studio really free?
Yes. Free is a plan, not a trial: Today’s Session, live pitch, 40 exercises, the 25 Foundations lessons, the range test and the tuner, with no card needed.
Do I need a Resono?
No. Any singer can use Rayvox Studio. The straw lessons work with any straw, and the guides for Resono Go, Resono Pro, Resono Flex and the SOVT book are free.
Which devices does it run on?
iPhone (iOS 15 or later), Android 7 or later, and the web at studio.rayvox.co.uk. Your account works on all three.
Is my voice recorded?
When you sing along, only your pitch is heard; nothing is recorded. Coaching Notes only reads lesson recordings you choose to upload.
