About NCW files
NCW files are proprietary audio files developed by the Japanese company NTT DoCoMo. They are used primarily in mobile phones and other portable media players. NCW files are not widely used outside of Japan and are not compatible with most audio players.
The NCW file format is based on the WAV audio format, but with an additional layer of encryption to protect the content from being copied. This makes it difficult to convert NCW files into other formats without specialized software.
The following software can be used to convert NCW files into other formats:
- Audacity (Windows, macOS, Linux)
- VLC Media Player (Windows, macOS, Linux, iOS, Android)
- Foobar2000 (Windows)
- various tools (Windows, macOS)
NCW files can be converted to a wide range of audio formats, including MP3, WAV, FLAC, OGG, and AAC. However, the encryption layer can make conversion difficult, and the quality of the converted file may be lower than the original.
Due to the difficulty of converting NCW files, we recommend using the free and easy online website Convert.Guru to convert NCW files. Convert.Guru supports a wide range of audio formats, including MP3, WAV, FLAC, OGG, and AAC. It also offers a high-quality conversion process, so you can rest assured that your converted files will be of the same quality as the original.
The NCW Converter Story
The history of Convert.Guru began more than 25 years ago in California, when Tom Simondi published the most comprehensive database of file formats on his website. Before that, Tom had worked on Space Shuttle development at the Air Force Systems Command’s Space Division in Los Angeles. He is known as one of the top programmers of the late 1980s.
When Microsoft integrated Tom’s Filext database into Windows XP, it became the leading platform for analyzing and processing file types and formats.
Today, we use the latest technologies to analyze, process, and convert one of the world's largest collections of file formats. We are committed to developing the best NCW converter by continuously improving quality, usability, and reliability.
