Fluctus Free is intended for editing audio. The application has an intuitive interface, so it is very unlikely that anyone with experience with this kind of tool can have difficulties to use it. The editor supports importing multiple audio file formats, such as AIFF, WAV, CAF, SDII, W64, FLAC, ALAC, MP3, AACL. Likewise, it allows extracting audio from various video extensions, including MP4, M4A, M4B, M4R, 3GP, 3G2, and MOV. In addition, you can import sound from any recording device.
Fluctus Free is, in many respects, similar to other audio editors: it lets you trim, cut, copy and merge audio segments as well as apply filters. However, what makes this tool different is that it supports using audio regions. Moreover, it comes with an intuitive marker system, which favors working with specific audio segments. Luckily, these markers can be exported to comma-delimited text files for future use.
However, mostly because this is the free version of a paid product, it has some limitations related to not allowing the export of audio in bit depths higher than 24-bit. Likewise, it does not support exporting 5.1 surround audio or saving the spectrogram as PNG or SVG picture files.
All in all, Fluctus Free can solve the most common problems involved in editing audio. It facilitates audio editing with various convenient features. Yet, it has some noticeable limitations in terms of exporting high-quality or 5.1 surround audio.
