Gaudio Lab is a South Korean AI audio technology startup, established on May 6, 2015. The company specializes in advanced AI audio solutions, including AI source separation technology and AI lyric synchronization technology. It has garnered international recognition, winning the Innovation Award at CES, the largest ICT convergence expo globally, and reaching the finalist stage in the audio experience category at the SXSW Innovation Awards, part of a major music/film/media festival in the United States. Gaudio Lab's technologies have been endorsed as standards by global standardization bodies such as MPEG and 3GPP. Gaudio Lab has 9 Ph.D. holders and 6 M.S. in acoustic engineering. This indicates that the company employs a professional sound engineering workforce that exceeds the size of those found in many large corporations, including Samsung Electronics.

Source Separation
This technology enables the extraction of individual sound sources from mixed audio signals that contain multiple overlapping sounds. This technology is used in various contexts like separating instruments (stem separation), extracting voices, getting rid of vocals, reducing noise, and making mixed reality (MR) experiences. Gaudio Lab's source separation technology boasts a high separation efficiency, achieving a Signal-to-Distortion Ratio (SDR) of 10.02. It is considered superior to similar technologies from major companies like Sony, Meta, and Deezer.

Spatial Audio
Spatial Audio is an audio technology that identifies the location of sounds and delivers them to the user's ears in three dimensions via binaural rendering. Gaudio Lab's spatial audio technology has been adopted as the MPEC standard. It can be implemented across various environments, including platforms, true wireless stereo (TWS) systems, and live streaming services.

Loudness Normalization (LM1: Loudness Management 1)
Loudness Normalization technology standardizes the volume levels across all content on various platform, ensuring an optimal playback for users. Gaudio Lab's loudness normalization technology is utilized in a range of applications including music/VOD streaming services, televisions, tablets, and mobile devices, etc. It has been established as a national standard by the Korea Telecommunication Technology Association (TTA) and also as an international standard by the Consumer Technology Association (CTA).

Generative Audio AI (FALL-E)
FALL-E is a generative sound AI technology designed to automatically create suitable sounds that complement specific content. Gaudio Lab’s FALL-E drastically reduces the processing time required for foley and sound effect creation, by more than 80%. To train FALL-E, 10,000+ hours of high-quality data were utilized. In March 2024, content featuring audio created by FALL-E was published, layered over video produced by OpenAI’s video generative AI, Sora. FALL-E was also showcased to Microsoft’s CEO Satya Nadella during his visit to Gaudio Lab's CES booth in 2024, who remarked "amazing", after experiencing the technology.

Just Voice
Just Voice is a real-time noise suppression solution that effectively removes background noises, delivering clear voice. It operates with ultra-low latency of 30ms and requires minimal computational resources, making it suitable for embedded systems. Just Voice can be applied on various operating systems, including Android, iOS, Windows, macOS, and Linux. The product earned the CES 2024 Innovation Award and was a finalist in the SXSW 2024 Innovation Awards under the Audio Experience category. Gaudio Lab released a macOS application called Just Voice Lite, which also features real-time noise cancellation.

AI Text Sync (GTS)
GTS represents Gaudio Lab's real-time lyric synchronization technology, where AI automatically aligns lyrics with sound sources swiftly and accurately. Unlike manual synchronization, which typically requires 240 seconds to sync a four-minute song, GTS accomplishes this in just 5 seconds. It also provides detailed syncing capabilities, including line-by-line and word-by-word adjustments. Currently, the technology supports Korean, English, Chinese, and Japanese languages.

LM1(Loudness Management Solution)
It is a loudness solution ready for OTT/music streaming. It reduces the loudness variance between sources to protect users’ hearing. Unlike in typical file-based solutions, the metadata-driven “server-client ” architecture eliminates the need for additional transcoding. It can set different target loudness for TV and mobile for one source saved in the server. It has been recongnized by Consumer Technology Association (CTA) and American National Standards Institute (ANSI) as an international standard. It won CES Innovation Award 2023 Honoree for streaming.

LM1 is a loudness solution designed for OTT and music streaming services, aimed at minimizing volume discrepancies between different pieces of content. This solution operates on a metadata-driven 'server-client' architecture, which eliminates the need for additional transcoding typical of file-based solutions. It allows for distinct target loudness settings for TV and mobile devices using a single audio source stored on the server. LM1 has been recognized as an international standard, adopted by both the Consumer Technology Association (CTA) and the American National Standards Institute (ANSI). It has also received the CES Innovation Award.

GSP - SA
GSP-SA is a fully software-based solution designed to facilitate the creation of spatial audio content without the need for professional hardware. It is optimized for streaming, boasting an exceptionally low latency of 0.26 seconds. When integrated with a video switcher and live streaming software, it automatically processes and transmits audio that is suited to the visual content of the scene.

Gaudio Spatial Audio (GSA)
Gaudio Spatial Audio(GSA) is Gaudio Lab’s proprietary high-quality spatial audio solution, which operates with an low latency of less than 0.05 seconds. Utilizing binaural rendering technology, GSA incorporates over 10 registered patents to accurately simulate psychoacoustic effects. The technology is versatile, supporting various audio formats including stereo, immersive audio, and ambisonics.

Gaudio Studio
Gaudio Studio is a source separation tool powered by GSEP, Gaudio Lab's proprietary technology that isolates individual instruments, voices, and noises. It is utilized for vocal removal, instrument practice, and karaoke(noraebang) track production. Notably, Gaudio Studio was rated the highest among five instrument separation software tools in an evaluation conducted by Music Radar, an international music publication.
