◆◆The road to using sound memo can be easily found◆◆
Soundmap is an application tool that can create recorded sound memos (voice memos) and lay them out like a mind map.
Starting with the idea of one sound memo, multiple configuration plans and recording takes are managed on the map.
Explore many possibilities by connecting fractions of ideas together and playing them back in a row!
(A mind map is a thinking tool that connects elements consisting of images like a tree to create a chart.)
“Record” “Connect” “Shape”
Let’s experience shaping sound ideas with Soundmap!

◆◆Main features of Soundmap◆◆
1. Start immediately by pressing Record
Start the app and start recording with just a single tap. Organizing an idea can be started on the map screen as is.
Also, since “re-recording” can be easily done by pressing the Record button on the editing screen, you can do it over and over until you create the memo you really want.
In addition, you can record while playing back other memos. You can also play back multiplexed memos, even while you’re editing.

2. Successive playback showing connection
Sound memos can be freely placed on map, making it easy to visually confirm the connections between recorded ideas. In addition, connection patterns can be checked by successively playing back the sound memo.

3. Connect with automatic cross fade. Easily edit the waveform
Because cross-fade is inserted between sound memos, they can quickly be checked for natural connections. In addition, a waveform editing tool that trims or cuts unwanted or blank recordings can be easily selected.

4. Customizable editing tool
Tools you often use can be set to the tool bar. These tools can be customized according to your style, with options such as cancel and redo for ease of trial and error or repeatedly making detailed edits.

5. Manage sound memos on a list
Sound memos can be managed on a list which can be shared outside the app. With iOS11 or higher, the “Files” app is supported and sound files can be smoothly imported.

6. More editing with the additional function menu
In addition, the following four functions can be added:
“Continuous playback of file, exporting projects”
To share on iOS, an idea formed from successive sound memos can be exported as a single file at the touch of a button.
Data placed on map can also be shared with other devices.
“Simultaneous playback of many memos”
Extends the upper-limit of sound memos that can be simultaneously played back to 10.
“Volume and tone adjustment”
Tone adjustment allows you to add EQ or reverb effects to each sound memo.
“Metronome function”
A metronome can be simultaneously played back when a sound memo is recorded. You can change the timeline display to beat display while the waveform is being edited. In addition, five types of metronome sounds are available.
