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.

f4v

F4V is a multimedia container format developed by Adobe Systems as an evolution of the Flash Video ecosystem. Introduced in December 2007 with Flash Player 9 Update 3, F4V is based on the ISO base media file format (MPEG-4 Part 14) and was created to support the H.264 video codec and AAC audio within the Adobe Flash platform. Unlike its predecessor FLV, which used a proprietary container structure, F4V adopts the standardized MP4-compatible atom/box architecture, making it more interoperable with other media tools and workflows. The format supports advanced features including high-profile H.264 encoding, multichannel AAC audio, and timed text for subtitles and captions. F4V represented a strategic move to address the growing demand for H.264 content on the web, as the older FLV container could not efficiently package this newer codec. During its peak years, F4V powered much of the high-quality video content delivered through Flash-based streaming platforms and video players on the web. The container supports both progressive download and dynamic streaming delivery, offering content publishers flexible distribution options. While the decline of Flash Player in favor of HTML5 video has reduced the creation of new F4V content, the MP4-based structure means the contained media streams are readily accessible through modern tools.

flac

FLAC (Free Lossless Audio Codec) delivers mathematically perfect audio reproduction at roughly half the size of an uncompressed WAV file. Maintained by the Xiph.Org Foundation and released in 2001, it quickly became the de facto open standard for lossless music archival. The encoder applies linear prediction to model each audio block, then codes the residual through Rice partitioning — exploiting the statistical distribution of prediction errors for strong compression without discarding data. Bit depths up to 32 and sample rates up to 655 kHz are supported, exceeding the requirements of high-resolution recordings. Hardware support is extensive: smartphones, car stereos, Blu-ray players, and virtually every desktop media application decode FLAC natively. Streaming services such as Tidal and Amazon Music use FLAC for lossless tiers, underscoring industry trust in the codec. Three standout benefits make FLAC compelling. First, complete bit-for-bit restoration of the original signal upon decoding. Second, embedded metadata via Vorbis comments and album art keeps libraries organized without sidecar files. Third, open-source licensing means no patents or royalties, removing legal friction for developers and hardware vendors.

Frequently Asked Questions

Why extract FLAC from F4V?

FLAC preserves every detail of the original audio without compression artifacts — ideal for archiving high-quality sound from F4V video.

What plays FLAC files?

VLC, foobar2000, Winamp, most Android music apps, and many modern car stereos support FLAC playback natively.

Is FLAC truly lossless?

Yes — FLAC compresses audio data without discarding any information. The decoded output is bit-for-bit identical to the source.

How large are FLAC files?

FLAC files are roughly 50-60% the size of uncompressed WAV while retaining identical audio quality — efficient lossless storage.

Can I batch extract audio?

Upload several F4V files at once and extract FLAC audio from each simultaneously — streamlined batch processing.
