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.

snd

SND is a multi-platform audio file extension used across several computing ecosystems since the late 1980s. On Sun and NeXT workstations, .snd files follow the AU format structure — a header with magic number 0x2e736e64, data offset, encoding type, sample rate, and channel count, followed by raw audio. On MS-DOS PCs, the same .snd extension was used by early sound utilities like Sounder and SoundTool for simple 8-bit unsigned PCM recordings. Macintosh systems also employed .snd for sound resources embedded in the resource fork. Because the extension is shared across incompatible formats, audio processing tools typically inspect the file header to determine which variant they are handling: files beginning with the AU magic number are treated as Sun/NeXT audio, while headerless files are interpreted as raw PCM with assumed parameters. The Sun/NeXT variant supports multiple encodings including mu-law, A-law, 8-bit and 16-bit linear PCM, and ADPCM, making it versatile for both speech and general audio. One advantage of the AU-style SND is its self-describing header, which enables any compliant player to determine sample format and rate without external metadata. The MS-DOS SND variants hold historical value as artifacts of the era when Sound Blaster cards first brought digital audio to personal computers. SND files from all platforms can be processed and converted using SoX and other audio tools.

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.

Frequently Asked Questions

Why convert SND to TTA?

SND lacks lossless compression. True Audio provides efficient real-time lossless encoding with hardware player support.

How do I open TTA recordings?

Play TTA with foobar2000, VLC, Winamp with TTA plugin, or TTA official decoder.

Can I tweak audio parameters before conversion?

Yes. You can set sample rate, bit depth, and channel configuration before converting your SND recording to TTA format.

Does SND to TTA conversion preserve audio quality?

When converting to lossless TTA, all audio data stays intact. Lossy formats reduce size through perceptual compression with negligible quality impact.

Can I convert multiple SND recordings to TTA at once?

Absolutely — add multiple SND recordings and convert the entire batch to TTA without processing files individually.

Is the SND to TTA conversion private?

Full privacy guaranteed. Your SND recordings are wiped post-conversion, and TTA results are deleted automatically within 24 hours.
