Our company develops a singing voice synthesis application for PC, and based on that architecture, we undertook implementation as an AUv3 plugin for iOS. However, requirements specific to singing voice synthesis—such as UI design premised on lyrics input, handling of large-scale models, and high initialization costs—are closely related to AUv3's execution model, sandbox constraints, extension launch restrictions, and iOS memory management characteristics.

In this presentation, we will organize the technical constraints we encountered in the process of realizing a singing voice synthesis application as an AUv3 plugin, and share perspectives that should be prerequisites when designing AUv3 in a mobile environment.

弊社ではPC向け歌声合成アプリケーションを開発しており、そのアーキテクチャを基にiOS向けAUv3プラグインとしての実装に取り組みました。しかし、歌詞入力を前提とするUI設計、大容量モデルの扱い、初期化コストの高さといった歌声合成特有の要件は、AUv3の実行モデルやSandbox制約、Extension起動時の制限、iOSのメモリ管理特性と密接に関係します。
本講演では、歌声合成アプリケーションをAUv3として成立させる過程で直面した技術的制約を整理し、モバイル環境でAUv3を設計する際に前提とすべき観点を共有します。
