Settings

The codec to encode the audio track. Codec "Without reencoding" copies the audio stream from the input file into output without re-encoding if possible.
Set the Vorbis encoder audio quality level. The scale is non-linear. The "Auto" mode produces roughly 112 kbps bitrate and is good in most cases.
Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).

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.

ogg

OGG Vorbis is an open, royalty-free lossy audio codec inside the Ogg container format, both developed by the Xiph.Org Foundation. Vorbis was designed as a patent-free alternative to MP3 and AAC, using modified discrete cosine transform (MDCT) coding with variable bitrate encoding that adapts to signal complexity per frame. Blind listening tests have consistently shown Vorbis delivering perceptual quality matching or exceeding MP3, especially in the 96-192 kbps range. The format supports sample rates from 8 kHz to 192 kHz and 1 to 255 channels, covering everything from mono voice to surround mixes. A standout advantage is the complete absence of licensing fees — game developers, streaming platforms, and hardware makers can implement Vorbis without royalty concerns. Spotify relied on Vorbis for years as its primary streaming codec for exactly this reason. The format also handles quality degradation at low bitrates more gracefully than many competitors, which is why it remains popular in video games where storage is tight and thousands of sound effects compete for space. VLC, Firefox, Chrome, and Android all provide native Vorbis decoding.

Open Standard

OGG Vorbis is patent-free and open-source — moving from TTA gives you freedom from proprietary format concerns.

Quality from Lossless

Encoding OGG from lossless TTA provides the encoder with perfect source — resulting in the cleanest possible Vorbis output.

Cloud Processing

Everything runs on our servers — no Vorbis encoders to install, no CPU load on your machine during conversion.

Frequently Asked Questions

Why choose OGG over TTA?

OGG Vorbis is open-source, patent-free, and outperforms MP3 at equivalent bitrates — while being far more widely supported than TTA.

What plays OGG files?

VLC, Firefox, Chrome, Android, foobar2000, most Linux players, and many game engines support OGG Vorbis natively.

How does OGG compare to AAC?

Both are excellent modern codecs. OGG is open-source and patent-free, while AAC has broader Apple ecosystem support.

Is the conversion lossy?

Yes — OGG Vorbis is lossy. But encoding from lossless TTA ensures the encoder gets perfect input for the best output quality.

Can I set a quality target?

Yes — pick from low to high quality settings, controlling the tradeoff between file size and audio fidelity.
