CODAA is a music application developed by KLABS Studio in collaboration with Pageno Music Vocal Training Center, bringing together music education, practice, analysis, and creative tools in one integrated mobile experience.

Created with the vision of making advanced music technology more accessible, CODAA is designed not only for experienced musicians but also for music students, aspiring singers, instrumentalists, educators, and anyone who wishes to explore the world of sound in their own way.

Where Technology Meets Music Education

One of CODAA's defining foundations is the collaboration between KLABS Studio and Pageno Music Vocal Training Center, combining technological development with practical experience in music education and vocal training.

Through this partnership, CODAA develops a range of learning and practice tools, with particular attention to students pursuing vocal studies, preparing for music entrance examinations, or seeking to strengthen their understanding of music theory.

Vocal training, ear training, rhythm exercises, sight-singing, and music theory are designed around structured learning approaches, supported by tools that help capture, analyze, and evaluate practice results.

Rather than simply listening to examples and repeating them, learners can visualize pitch, monitor their performance, and identify areas for improvement throughout their practice sessions.

CODAA aims to transform musical concepts that may otherwise seem abstract into intuitive, accessible, and interactive learning experiences.

A Dedicated Space
for Music Learning and Practice

CODAA brings together a variety of tools designed to support the development of musical knowledge and practical skills.

Vietnamese Interface. English Included In-App

Vocal Training and Vocal Range Exploration: Users can practice with reference sounds, track vocal pitch, and observe visual representations of their performance. These tools help learners better understand pitch control and vocal range.

Ear Training: Interactive listening exercises help develop the ability to recognize, remember, and reproduce sounds, melodies, and relationships between musical pitches.

Rhythm Training: Through listening and rhythm reproduction exercises, learners can strengthen their sense of timing, rhythmic accuracy, and musical coordination.

Sight-Singing and Music Notation: CODAA supports reading musical scores, recognizing pitch and note duration, and developing the connection between written notation and actual sound.

Music Theory: Developed with the educational involvement of Pageno Music, this learning area focuses on strengthening foundational knowledge and supporting examination preparation, particularly within the context of music education in Vietnam.

A Versatile Audio Analysis
and Processing Workspace

Beyond music education, CODAA also provides a flexible workspace for people who regularly work with audio and music.

The application brings together tools for detecting musical keys, chords, tempo, rhythm, and musical structure, while also supporting pitch adjustment, playback speed control, audio analysis, and various forms of sound processing.

These tools can assist users in studying musical compositions, practicing alongside recordings, exploring chord progressions, preparing performances, or supporting songwriting and music production.

Features such as vocal and instrumental separation, audio editing, silence processing, and support for music-related file formats make CODAA adaptable to a wide range of creative and technical needs.

CODAA is not intended to completely replace professional desktop music production software. Instead, it focuses on delivering practical, intuitive, and accessible tools within a convenient mobile environment.

Exploring the
World of Musical Instruments

Music is expressed not only through symbols written on a score, but also through the physical interaction between musicians and their instruments.

CODAA develops interactive instrument simulations and visualizations, including piano, guitar, and ukulele, allowing users to explore note positions, chord structures, and the relationships between musical sounds.

These experiences are designed to connect theoretical knowledge with practical understanding, helping learners visualize musical structures, discover chord fingerings, and understand how individual notes interact.

Additional tools, including a metronome and instrument tuning features, contribute to a more convenient and comprehensive practice environment.

Technology as the Foundation,
Music at the Center

CODAA is built upon digital signal processing, audio analysis, and modern recognition technologies.

Through its SoundCore music technology platform, the project aims to establish a connected foundation for a wide range of capabilities, from audio recognition and analysis to simulation, interactive training, and sound processing.

One of CODAA's priorities is to make use of on-device processing whenever technically feasible, reducing dependence on remote servers and giving users greater control over their working data.

Recognition and analysis results are intended to serve as supporting tools. Depending on audio quality, musical characteristics, and intended use, users may still need to review and adjust the generated results.

We believe the true value of technology lies not in replacing human musical expression or creativity, but in expanding what people can achieve through them.

Designed with an Understanding
of Music Education in Vietnam

CODAA places particular emphasis on the experience of Vietnamese users, from interface language and educational presentation to the practical requirements of music study and entrance examination preparation.

The collaboration with Pageno Music provides valuable educational insight, helping the project develop learning materials that reflect local teaching practices while incorporating modern music analysis technologies and approaches.

This also reflects one of CODAA's long-term goals: to create music tools that offer meaningful technical and educational depth without placing unnecessary barriers in front of beginners.

By combining accessible design with specialized capabilities, CODAA seeks to support learners at different stages of their musical journeys.

A Continuing Journey of Development

CODAA is an evolving project, continuously being refined and expanded.

Its existing features provide the foundation for further research, improvement, and development of tools that support music education, performance, composition, and exploration.

We welcome feedback from users, teachers, students, musicians, and the wider music community. Every suggestion offers an opportunity to make CODAA more accurate, more intuitive, and more useful in real-world situations.

CODAA is more than a collection of music tools. It represents an ongoing effort to bring musical knowledge, technology, and creative inspiration together in one connected space, where everyone can learn, practice, and explore music in their own way.
