What It Is

Ruomu Studio is an app developer focused on mobile audio creation. This review covers EZAudioCut-MT, EZAudioCut, and Au Audio Editor. These products primarily serve recording, editing, mixing, and audio post-production needs on iPhone, iPad, Android phones, and tablets, positioning themselves closer to mobile audio workstations and recording/editing tools.

Core Capabilities

In terms of features, the product lineup is fairly comprehensive: EZAudioCut focuses on single-track recording and editing, offering high-precision trimming, undo/redo, volume envelope adjustment, EQ, reverb, chorus, speed and pitch changes, voice noise reduction, and silence removal. EZAudioCut-MT and Au Audio Editor place more emphasis on multitrack mixing, supporting up to 64 tracks, making them suitable for cover songs, backing-vocal recording, and stem-based production. Au also highlights vertical-screen multitrack editing, batch export, a metronome, recording monitoring, project sharing across devices, and AI accompaniment/vocal separation.

Pricing and Copyright

The collected text does not disclose specific pricing, subscription models, in-app purchases, or free-tier limitations. It also does not clarify commercial-use licensing, ownership of user-created works, or the boundaries of copyright responsibility for accompaniment/vocal extraction. Therefore, before using it for commercial content production, users should still check the App Store, Android download page, or the official privacy/terms pages.

Pros and Cons

The advantages are strong mobile adaptation, with support for phones and tablets; EZAudioCut also supports Apple Watch remote and offline recording. Its audio-processing capabilities are also relatively complete, including RNN noise reduction, pitch shifting, reverb, EQ, delay, accompaniment extraction, and support for external microphones and Bluetooth devices. For export, it supports formats such as AAC, M4A, MP3, WAV, and AIFF, and offers sharing channels including email, SMS, WiFi, iCloud, WeChat, and QQ.

The drawbacks lie in limited information transparency: pricing, licensing, customer support, and the size of the resource library are not specified. Collaboration features appear limited to project sharing between devices, with no description of multi-user collaboration or team workflows. Since multiple products have overlapping features, first-time users may need to try them before deciding which one to choose.

Who It’s For / Access in China

It is suitable for users who need mobile audio editing, cover-song recording, podcast narration processing, voice noise reduction, and lightweight multitrack mixing. Access from China cannot be confirmed from the reviewed text; whether the domain and download links are stable would require actual testing, so it is currently rated as unknown.
