Settings

Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).
Set the sample rate of the audio. Music with a full spectrum (20 Hz — 20 kHz) requires values not lower than 44.1 kHz to achieve transparency. More info can be found on the wiki.
Adjust the audio volume by selecting a number of decibels. For example, -10 dB decreases the volume by 10 decibels.

flv

FLV (Flash Video) is a container format originally developed by Macromedia and later maintained by Adobe Systems after the 2005 acquisition. The format gained support for standalone playback with Flash Player 7 in 2003 and quickly became the dominant video format on the web, powering platforms like YouTube, Hulu, and Vimeo during the late 2000s. FLV files typically contain video encoded with the Sorenson Spark or VP6 codec alongside MP3 or ADPCM audio, wrapped in a lightweight proprietary container optimized for streaming delivery. The major strength of FLV was its ability to deliver consistent video playback across different operating systems and browsers through the ubiquitous Flash Player plugin, solving the fragmentation problem that plagued web video at the time. FLV files begin with a compact header followed by tagged data packets, a structure that enables fast seeking and efficient progressive download. The container supports embedded metadata with cue points, enabling interactive features like chapter navigation and timed events. FLV transformed online video from an unreliable niche experience into a mainstream medium, fundamentally reshaping entertainment, education, and communication on the internet. Although HTML5 video and modern codecs have replaced Flash-based delivery, FLV files remain in countless archives and legacy systems.

tta

TTA (True Audio) is a real-time lossless audio compression codec developed by Aleksander Djourik, with its origins tracing back to the early 2000s. The format reconstructs the original PCM stream bit-for-bit upon decoding, guaranteeing that no sonic detail is lost during storage or transfer. TTA handles standard CD-quality audio as well as high-resolution content up to 32-bit integer samples, making it suitable for everyday listening and professional archiving alike. Processing speed is one of TTA's defining strengths — the codec achieves fast encoding and decoding without heavy CPU demands, keeping it lightweight even on older hardware. The file structure supports ID3v1, ID3v2, and APEv2 metadata tags, so track information and album art travel with the audio. Hardware support appeared in several portable players, giving TTA a practical edge over some competing lossless formats. The open-source reference implementation ships under the GNU GPL, encouraging community adoption and third-party integrations. While newer codecs like FLAC have captured a larger share of the lossless audio landscape, TTA continues to serve users who value its simplicity and transparent compression.
