The SoundVQ Encoder using TwinVQ Technology, produces very high quality compressed audio files (.VQF) which are smaller in file size if compared to a same audio file encoded as .MP3 - and because of this high quality compression, encoding takes a fairly long time. The results are worth it tho' IMO. Also: Modern media players such as VLC can play SoundVQ's .VQF audio files.

   A proprietary audio compression format called TwinVQ was developed by Nippon Telegraph and Telephone Corporation (NTT) (in NTT's Human Interface Laboratories) and marketed by Yamaha under the name SoundVQ. Yamaha marketed TwinVQ as an alternative to MP3, but the format never became very popular. [...] As other MP3 alternatives emerged, TwinVQ quickly became obsolete.

   The proprietary version of TwinVQ can be also used for speech encoding. Compression technology specifically designed to handle voice compression was published by NTT. The NTT TwinVQ implementation supported sampling frequencies from 8 kHz or 11.025 kHz and bit rate from 8 kbit/s.

Yamaha produced a free player, "SoundVQ Player" and separately, an encoder "SoundVQ Encoder" for creating ".vqf" files on Macintosh (also released for Windows platforms).

Top download above is for the SoundVQ Player.

Architecture: PPC

For PPC Macintosh only, including Mac Clones & SheepShaver.

Note: The SoundVQ Encoder is time-bombed to expire at 90 days.

A Workaround for the 90 day Encoder time limit:
(Step 1). Using the Unhide Tools "Change File Visibility" feature; Drag the "Preferences" folder inside your Mac's System Folder onto the "Change File Visibility" icon to show a window containing the Preferences folder's contents. Inside of this window, scroll down and locate the hidden file named "svqdat011". Place a check into the empty box to the immediate left of the "svqdat011" file-name. Quit the Unhide Tools and open the actual "Preferences" folder. The file named "svqdat011" will now be visible. Locate and send it to the Trash.

(Step 2). Using ResEdit's Open File dialog, locate & open the Application "SoundVQ Encoder 2.52eb7" (or simply drag the SoundVQ Encoder's icon onto ResEdit's application icon to launch & open its resources for editing) and delete the resource labeled "DaTe". Save changes & Quit ResEdit then run SoundVQ Encoder. A fresh date-stamp & "DaTe" resource gets created.

This will give you another 90 days usage. Repeat the above two steps as required.

@mrdav: Done. Looking at work-around for the time-bombed encoder now.

[Edit] (1). Using ResEdit, make the invisible Preference file named "svqdat011" in the System's Preferences folder visible, Save, close, then manually delete it.
Also, (2). Using ResEdit, open the "SoundVQ Encoder 2.52eb7" application and delete the resource labled "DaTe". Quit REsEdit and run SoundVQ Encoder, a fresh date stamp & "DaTe" resource gets created. This will give you another 3 months usage. Repeat these two steps as required.
[Edit 2]: Step (1) above, its slightly easier/faster to alternatively use the Unhide Tools instead, for this task.

--------Anyhoo, if necessary I can upload these.-----

Yes, please do, or the page is of no use.

@mrdav: these files are fubar. I've since done a wayback search on yamaha software and have located a "vqe252b7e.hqx" & a "vqp250b2e.hqx" in good shape. Despite their ".hqx" suffix extensions, both are actually ".sit" files! The two from here, are damaged ".hqx" tho'.

The two I've recovered contain the player & the encoder respectively. However the encoder is time-bombed at 90 days after installation. - Anyhoo, if necessary I can upload these.

The two hqx downloads seem to be corrupted. They unpack to a files of zero size. Also the headers in the hqx files are wrong, but it made no difference when I corrected the headers. Anyone able to replace the files with good copies?

EDIT: You can see more evidence of the corruption to the hqx files by opening them up in a text editor. There are some lines that are longer than the required 64 characters and I have found at least one non-ASCII character! Simple attempts to realign the text to 64 characters and removing the non-ASCII characters does not improve matters, so the problems are deeper than a simple formatting error.
