All Convert products are designed to handle high-resolution audio output, in addition to almost every standard audio format, to ensure the best possible audio experience. Each product is also equipped with HD video, so you can create the magic of immersive cinema in your home. To ensure unrivalled device UPnP compatibility and seamless playback when handling varied audio qualities, Convert has integrated some unique technologies.
High Resolution Audio
Convert products ‘up-sample’ the audio they play back by default (although you can change this setting) to 24Bit / 192khz, using a process known as ‘cuboid interpolation’. This mathematical algorithm process fills in the sampling gaps caused by the up-sampling of ‘lesser’ formats to ‘smooth’ out the audio wavelengths you hear. If your audio file / input is sampled well enough, no up-sampling will be required.
The challenge with this, is that 24Bit / 192khz is such a good bit depth and sample rate, that many devices and satellite speakers cannot play it back because they don’t have the processing power to do so. So… how does Convert deal with this? If the device ‘receiving’ the signal is built / designed well enough, it will be able to communicate with Convert, and let your Convert product know that it will struggle with that level of quality. Once duly notified, Convert can then switch down to the appropriate bit and sample rate, so that the device can then play back the audio to you. Smart stuff and focused on quality.
Supported Audio Formats
RAW audio data that audio hardware processes. One of the reasons WAV file formats are so big, is because its data is held in the form of high resolution PCM data
Uncompressed, lossless, an exact high resolution recording of the sound. Often HUGE file size
Uncompressed, lossless like WAV, but designed and implemented by Apple for Apple products
Compressed, lossless, exact recording of the sound. The files are big, but Convert achieves around 50% compression ratio versus WAV, meaning they’re far more portable. (This is why we use this high resolution format so widely.)
Compressed, lossless, the Apple version of high resolution FLAC. Outside of Apple products, this format is rarely supported
Compressed, lossy, small file sizes. More recent version of MP3, with better performance. A standardised codec, this format is well supported by all platforms – including Apple
Compressed, lossy, small file sizes. This is the ‘original’ standard audio format, and is hugely supported. However, because of its age, it may become obsolete by AAC
Compressed, lossy, open-source format similar to AAC and MP3 – but with limited use across most platforms
High Resolution Video
Convert Products can play video content up to 1080p high-resolution. Each is equipped with an HDMI output to connect directly to a TV, or to stream video media via the Wifi network to any UPnP compliant device.
Using video on Convert products is really simple. Import the file, then using the app, select the file you want to play, the destination visual device to play it to, and away you go. You can even use your hifi speakers to render the video-audio output.
Supported Video Formats
An older compression standard that is now considered to be obsolete
Based on jpeg. Widely supported by wed browsers and computer video players, including native support in Quicktime. Much simpler than H264, but nowhere near as good compression
Widely used for over the air digital TV and is usually the format used on DVDs. Not as efficient as newer standards such as H264
H264/MPEG4 AVC (MP4)
One of the most widely used and supported formats. Defined within MPEG4 part 10 (but MPEG4 files can use other codecs). Supports higher resolutions than H263, including 1080p. Has higher quality and lower bit rates than H263, which is why it is widely adopted and supported
Owned by Google but released as an open and royalty free standard. Broadly equivalent to H264 but without the need to use patented technology and pay license fees. Supported by many web browsers and other platforms
MPEG4 part 2. Earlier codecs than H264. Designed for lower bit rates and resolutions in things such as mobile phones. Comparable to H263, and fast becoming obsolete
A codec that implements MPEG4 part 2 ASP, with all of the extra features and functionality that entails. You’ll find lots of high resolution videos in this format
The ‘Matroska Multimedia Container’ is an extremely popular open standard, free container format. As a file format it can hold an unlimited number of video, audio, picture, or subtitle tracks in one file. It is intended to serve as a universal format for storing common multimedia content, like movies or TV shows. (Especially important if you want to use subtitles.) MKV is similar in concept to other containers like AVI, MP4, or Advanced Systems Format (ASF), but is entirely open in specification. Matroska file extensions are .MKV for video (with subtitles and audio), .MK3D for stereoscopic video, .MKA for audio-only files, and .MKS for subtitles only. You’ll see a lot of high resolution films and TV box set digital files in this format
