Open the Audio settings with the Audio button on the Menu bar. In order to get the best out of Deckadance, you may need to take some time to familiarize yourself
with the Audio options here and the Preferences.
Deckadance uses both audio inputs and outputs. Inputs are used to accept control signals from vinyl/CDJs and from microphones for PA (Public Address). Windows users
- it is strongly recommended that you select an ASIO driver (ASIO4ALL for example) as Deckadance will run more smoothly with ASIO.
NOTE:With the ability to use of 5 pairs of audio inputs and 6 pairs of outputs, you may find it useful to aggregate the inputs/outputs from several audio interfaces in Deckadance.
Windows users can use ASIO4ALL while OSX, Mac users can use the Aggregate Device
Editor. The options that show in the INPUT/OUTPUT dropdown menus above depend on the audio interface/s connected to your computer.
- Audio device type - Select the audio driver type. PC: ASIO or Direct Sound (ASIO recommened). Mac: This option is not available.
- device - Selects your soundcard/audio & driver. PC users: We recommend using the ASIO4ALL driver if you don't have specific hardware in mind. The Deckadance installer includes
- Test - Tests the Left and Right channels.
- Sample rate - Select the play-back frequency of your audio interface. 44100 Hz (44.1 kHz) is most common although some interfaces use 48000 Hz (48 kHz).
- audio buffer size - This is a working buffer (breathing space) used to avoid CPU overload. As the latency is increased the delay between moving a MIDI/interface control and
hearing/seeing the result is at least equal to this setting (in ms). The ideal buffer is the smallest your computer can manage without causing glitches. Notes:
- Generally - For most DJ work there is no need to set a latency below 256 samples (~5 ms @ 44.1 kHz).
- Elastique - When Elastique master tempo engine is active, a minimum suggested latency is 128 samples. We also recommend multiples of this latency in case longer latencies
are required: 256, 512, 1024, 2048.
- DVS - For DVS 'scratching' we suggest that you disable the master tempo engine and reduce the latency as low as possible around (88 samples for an average computer and soundcard
with good ASIO drivers).
- show this device's control panel - Opens the soundcard driver interface. Windows: If your audio interface does not have native ASIO drivers we recommend using
soundcard driver. This allows you to use more
than one audio input/output device.
The number of inputs available depends entirely on the Audio Device (soundcard, mixer or audio interface) you are using.
- INPUTS - Select audio input configuration. Your ability to use the options below will depend on the number of inputs your audio interface has:
- No inputs - Using only Deckadance internal decks.
- Mic - Using a single microphone input. You will either be announcing or singing. If you think you can sing, check with friends first! Your mother's opinion does not count.
- Input decks - You can have any combination of Vinyl or CDJ decks to a total of 4.
- Input decks + mic - You can have any combination of Vinyl or CDJ decks to a total of 4.
The number of outputs available depends entirely on the Audio Device (soundcard, mixer or audio interface) you are using.
- OUTPUTS - Select audio output configuration for internal or external audio mixing. Your ability to use the options below will depend on the number of outputs your audio interface has:
Setting up your inputs & outputs
- Click the Audio button.
- Select a soundcard - From the Audio Interface field, select a driver (see the screenshot above). This is your Soundcard or audio interface device labeled by the name of the
soundcard driver. Options available in this menu depend on the soundcard devices connected to your computer. Windows users will have access to the
ASIO4ALL universal soundcard driver included in the Deckadance installation. This will allow you to aggregate several audio devices into one to
work with Deckadance. OSX, Mac users can also check out the 'Aggregate Device Editor' that allows you to set up custom
inputs/outputs from multiple audio devices also.
- Select a sample rate - 44100 Hz is the preferred default CD audio rate, however some soundcards, such as the Creative Audigy series, are limited to 48000 Hz (minimum).
- Set the soundcard latency - Open the Control Panel (ASIO settings) and adjust the soundcard latency. This is a working buffer with which
Deckadance performs mixing operations. Generally, shorter latencies put more load on your CPU (which can cause audio stuttering), however short latencies
are desirable for greater 'responsiveness' when scratching, for example. Soundcard latency is expressed in milliseconds or samples. 20 ms (882 samples @ 44.1 kHz)
is sufficiently short for most DJ work. 10 ms or less (441 samples @ 44.1 kHz) ) is desirable if greater responsiveness is required. Experimentation will help you
to determine what is suitable for your needs.
Eliminating audio glitches: The shortest latency achievable without overloading the CPU and stuttering, will depend on your soundcard and computer speed. There are a number of
options on the General, File & MIDI Settings panel that can aid in reducing CPU load and stuttering if you find increasing the latency AND using an ASIO driver is not successful. Try
selecting the 'Slow decoder analysis mode' & 'Disable Elastique master tempo and keylock engine' options.
- If you have more than one soundcard, or wish to use independent INPUT and OUTPUT devices, you can use the ASIO4ALL driver. This should make all the
INPUTS/OUTPUTS on your audio devices available on the drop-down menus for each INPUT/OUTPUT category. Follow this link for more details.
- Headphone Mix - It is often useful to monitor decks while cueing tracks, without sound being passed to the Main Outputs of Deckadance.
Where you see headphone symbols on the main interface, it means that an output can be sent to the Monitor Buss (usually a separate mix for the DJs
Headphones). To set up this feature, you need to have either multiple audio devices or a soundcard with more than one output. If your soundcard has
surround-sound capability, for example, you can use the rear channels to feed your headphone mix and select those in Monitor Left and Right settings in the
Audio & MIDI Setup panel. In another 'low rent' approach, many USB headsets used with Skype etc, have a built in mic and are also headphones. These will
appear as a USB audio device and will allow you to use the PA feature (from the mic) and to monitor your cueing, all hands-free (but is it cool? who knows!).
