Learn the harmony before your next band rehearsal. Split a song into lead vocals, harmony and backing, loop the part you want, and change the key. 3 songs free.
Hamoru is a practice app for people learning harmony parts. It splits a song into lead vocal, harmony, and backing so you can listen to each part.
What it does
• Import an audio file or a video, and it is split into three parts, lead vocal, harmony, and backing, right on your iPhone.
• Set the volume of each part. Listen to the harmony alone, or blend in a little of the lead.
• Mark a section and loop it. Name and save sections, then tap one to switch to it.
• Change the key in half steps, up to six half steps up or down.
Pricing
You can separate up to three of your own songs for free. After that, a one-time in-app purchase removes the limit. There is no subscription.
Your songs stay on your device
Separation runs on the iPhone itself, and your songs are never uploaded. The AI models are built into the app, so separation and playback work without an internet connection.
Before you start
• Songs up to 10 minutes long can be imported.
• Separation takes several minutes or more, depending on the device, the length of the song, and how warm the phone gets. It also needs some free storage to prepare.
• Results vary from song to song. Some lead vocal or instruments may remain, or the harmony may come out faint. Please try your own songs with the three free separations first.
• If a song has more than one harmony voice, they can't be split into separate parts.
• Songs can't be imported from streaming services' links or playback screens. Use audio files or videos you have the right to use.
• Supported devices: iPhone 15 Pro, iPhone 15 Pro Max, and the iPhone 16 series or later (iOS 26 or later). Earlier iPhones and iPad are not supported.
