Upsampling audio magic


Everything that passes through the Stream Magic 6 is upsampled, using our unique ATF2 (Adaptive Time Filtering) process, developed in conjunction with Anagram Technologies of Switzerland, through a high-end Analog Devices DSP (Digital Signal Processor), to ultra-high detail 24-bit 384kHz output.

As well as dragging extra detail from every source (even CD, Blu-ray and "Lossless" digital files), ATF2 virtually eliminates "jitter" common in playing digital audio files – which can lead to a flatter, lifeless sound with tinnier bass response. Those problems vanish when digital audio's put through Stream Magic 6.

Network audio magic for wireless musicupnp support

Streaming network audio to your hi-fi's easy with Stream Magic 6. Music on wi-fi connected* desktops, laptops and NAS drives is automatically detected to create a wireless music system. And, of course, all those digital audio files, upsampled through the Stream Magic 6's unique ATF2 process, will sound far better through your main hi-fi, than desktop speakers.

*UPnP-supported devices only. Most modern laptops, computers and network (NAS) drives are UPnP-supported as are many games consoles, streaming boxes and smartphones.

ATF2 Upsampling in more detail…

Stream Magic 6 makes digital audio sound amazing – drawing detail seemingly out of thin air. How?

Our unique ATF2 (Adaptive Time Filtering) upsampling technology, developed in conjunction with Anagram Technologies, Switzerland.

logo-upsamplingAll incoming audio data, such as CD at 16-bit 44.1kHz CD, is upsampled to 24-bit 384kHz using a high-end 32-bit Analog Devices DSP (Digital Signal Processor). "Polynomial Curve Fitting Interpolation" provides a much more accurate upsampled audio soundwave than traditional upsampling processes. And a unique timing system buffers audio data to almost eradicate digital jitter. Vital – as jitter, common in digital audio devices, loses vital detail, often leaving digital audio sounding flat and lifeless.



Our latest ATF2 DSP also features a selectable digital filter with three settings to suit listener preferences and their particular system set-up: 

• The Steep roll-off filter exhibits strong attenuation of aliasing images outside the pass band (i.e. above 22.05kHz) at the expense of a little pre and post-ringing in the time domain. 

• The Linear phase filter uniquely features ‘constant group delay’ which delays all audio signals at all frequencies by the same amount meaning all audio is fully time-coherent at the output.

• Minimum phase meanwhile does not feature constant group delay but rather the co-efficients have been optimised without feed-forward so that the impulse response exhibits no pre-ringing in the time domain.

The symptom is audio cutting out after 3 minutes of playback with some aptX capable source devices. Typically affected devices will be Samsung Galaxy S3 Android phones and Apple computers.

If you have any previous version of the update app installed on your PC, you should uninstall this first:

Windows 7 / 8 - ‘Control Panel → Programs and Features’ and double clicking on any installed instance of ‘BT100 Update’.

Windows XP - ‘Control Panel → Add and Remove Programs’ and double clicking on any installed instance of ‘BT100 Update’.

Full instructions from a fresh install are then included in the zip file; please read them first. Click here to download BT100 upgrade files and instructions - note: this upgrade can only be carried out on a Windows computer.
