Otokago — Quick Start

A library manager and player for ASMR / doujin audio works — for Windows

Get going in three minutes

Otokago lists your audio works album by album and lets you narrow them down by tag, voice actor and circle. Point it at a folder, scan, and your library is ready.

Install
Run the installer and follow the prompts. The installer is available in English and Japanese. Windows 10 / 11 (64-bit) is required; about 400 MB of free space plus room for the database.
Add your folder
On the first launch the library is empty. Press "Choose folder" and pick the one parent folder that holds your work folders. You can change it later from Settings → Library → Folder to scan → "Change folder".
Scan
Scanning starts automatically once the folder is set; a large library can take a few minutes. After you add new works, press "Rescan" in the sidebar (or F5) to pick up the difference.

Your audio files are never copied or moved. Otokago only references them where they already are, so your folder layout stays exactly as it is.
Filter
Use the sidebar for Status (All / Unplayed / Played / Favorites / Recently added / Recently played), Length and Extras. Use the buttons above the grid for tags, voice actors and circles — multi-select and exclusion are both supported, and every candidate shows a live count so you never filter your way down to zero. Ctrl + F searches by work title.
Play
Click a cover to open the work, then click a track to start it. Use the player bar at the bottom, or the right-hand panel for the ASMR tools (sleep timer, reverb, EQ, vocal boost, volume levelling, balance, speed, crossfade, A-B repeat, album shuffle). Press C for the mini player: the window shrinks and stays on top of your other windows.

The library grid, with state / length / extras filters on the left and album covers in the middle — The library. Filters on the left, covers in the middle, the player bar at the bottom.
Screenshots show the Japanese interface; the layout is identical in English.
Screenshots use demo data. All work, circle and voice actor names shown are fictional.

The filter drawer open, showing tag candidates with counts and the selected tag as a chip — The filter drawer. Selected conditions stay visible as chips above the grid.

Playback in progress, with Now Playing, L/R meters and the ASMR tools in the right panel — Playing. The right panel summarises which effects are currently active at the top.

The mini player: cover, track title, transport controls, seek bar and volume in one row — The mini player (`C`). "Restore" puts the window back exactly where it was.

Album name roots — keep album names correct

When an audio file's tags carry no album name, Otokago uses the name of the folder that directly contains the file. Many doujin audio works ship as "Work title / mp3 / audio files" — scanned as-is, such works get registered under the subfolder name (e.g. "mp3"), and works without an RJ code in their folder names may even be merged into one album.

To prevent this, open Settings > Library > "Album name roots" and register the parent folder that holds your work folders (e.g. D:\voice). The folder names directly under it are then used as album names, regardless of how the inside of each work folder is organised. Set this up before your first scan — Otokago will remind you once if you start a scan without it. If some works were already registered under a wrong name, delete those albums from the library (your audio files are not touched) and scan again.

Frequently asked

What are the limits of the trial version?

The trial registers up to 30 albums. Every other feature works, including filtering, the ASMR tools, scripts and the converter.

Data made in the trial carries over to the full version as it is. You do not have to re-enter tags, favorites, scripts or registered work information. Installing the full version on the same PC completes the move — no rescan is needed.

Does this app use the network?

The app does not use the network. There is no telemetry and no automatic update check, and no external fonts or CDNs are loaded. "Open on DLsite" on a work's detail screen only hands the link to your default browser; the app itself does not connect anywhere. Your library, tags and playback history are stored only in a database file on your own computer and are never sent to the developer or any third party. See Article 3 of the bundled End User License Agreement for details.

How do I get support?

Questions and bug reports are handled through the message function on the product page of the store you bought it from. Please attach the contents of Settings → About → "Diagnostics" and the error log (Settings → Data → Locations → "Error log"), along with what you were doing at the time.

The app never checks for updates by itself. New versions are provided as a re-download from the store you purchased from, and installing over the previous version keeps your data and settings.
