If you feel your computer in Windows is slow for DJing, you should check the following settings.
1) Switch off the Wifi, Bluetooth, and any other network connection on your computer before a DJ performance. Network connections consume CPU ressources and may cause crackles in the music. Letting the Wifi receiver switched on is the most dangerous setting for DJing on a computer, since each time the Wifi receiver of the computer detects another Wifi source, the CPU ressources of the computer will drop of 50%: if someone in the street has a smartphone with Wifi on, your computer detects this Wifi source, scans it, and this Wifi identification process takes up to 50% of the computer CPU ressources, possibly causing crackling.
2) Disable Windows preset made to save energy on the USB. This preset is set on by default, and it may cause crackling in the sound, and even disconnect the DJ controller on the computer.
Right-click on My computer > Properties > Device Manager > Universal Serial Bus controllers,
Right-click on the first line "USB Root Hub" and click "Properties"
Go to the tab "Power Management", and uncheck the box "Allow computer to turn off this device to save energy"
Click "OK" and close the dialog box
Repeat the same operation on each line called USB Root Hub or USB hub.
3) Close any background software Real time operations as Djing or video capture require to as much CPU ressources as possible, so you should close any other background software during a DJ performance.
4) If possible, move the mouse far from the USB port where you plug the DJ controller If the USB port of your mouse is close from the USB port of your DJ Controller, and if you have enough USB ports for it, you should plug the DJ Controller on a USB port far from the mouse USB port, as the click on your mouse may be heard in the audio played on your DJ controller if the USB port are close one from the other.
5) In Windows 7 or in Windows Vista, avoid Aero graphic theme. Aero graphic themes are CPU intensive, so don't use an Aero graphic theme while doing any real-time task as music production or video capture, select a basic theme instead.
6) Adjust your computer settings for the best performance - Go to Start > right click on Computer > Properties > Advanced System settings > "Advanced" tab. - Click on "Settings" in the "Performance" area. - In "Visual Effects", click on "Adjust for best performance", and press "OK".
7) If you use a laptop, set your "Power plan" on "High performance". Go to Start button, and in the search bar, type power settings The "Power Options" menu lets you can select your power plan among three preset plans: Balanced, Power saver, or High performance. Select the High performance power plan.
8) Don't let any USB key connected on the computer You can use USB keys to copy an audio track on or from your computer, but once it is over, unplug it from your computer. USB keys have a slow access time (even USB keys with a fast transfer rate have a slow access time), so if they are connected to the computer, they decrease significantly the computer performance even for task which don't use the USB keys. Never play an audio track directly from a USB key: if you uncompress an audio track on a USB key, the access time of the USB key is so slow that you complete computer because slow. If you want to play a track stored on a USB key, copy it on your hard disk prior to playing it.
9) Make sure your disk is not saturated, DJing requires a large available hard-drive space Windows needs hard drive space to be fast, and playing music requires a significant hard disk space. When loading audio tracks, the audio tracks are uncompressed in the software and need, either in the hard drive + in the RAM, the same space as if they were in an uncompressed WAV format, even if they are stored in a compressed format as MP3, AAC or WMA. Examples of hard drive + RAM needed to uncompress 2 tracks of 10 minutes
16-bit/44.1 kHz, 2 tracks of 10 minutes = 201.8 MB
Most DJ software with a recording function let the Deejay record in Wav format. Some of you wonder how to convert the .wav file into MP3 format to share your creation. Here is a process to do it in Windows with iTunes 11.2.
1) Start iTunes
2) Click on iTunes rectangle on the upper-left corner
3) Select the Preferences menu
4) In the General Preferences, go to “Import Settings…”.
5) In the Import Settings, select Import using “MP3 Encoder”
6) In the Import Settings, click on the Setting field to set for the MP3 compression rate.
7) If you select the “Custom” setting, you can select the compression rate you wish.
Click on OK to close.
8) You can check your compression settings in the field “Details”.
Click on OK to close.
iTunes is now set to convert files into the MP3 format you have selected.
9) If the file you want to convert is not in iTunes library, add this file in iTunes library.
Import your .wav file in iTunes.
Click on the rectangle icon in iTunes upper-left corner, and choose “Add File to Library…”.
Browse to your .wav file, select it and click on Open.
10) Once the audio file is in iTunes libray, right click on it in iTunes and select “Create MP3 Version”.
11) iTunes converts it into MP3 format.
12) Once iTunes has created a MP3 version, it is located by default in a folder
To check where it is located, right click on the created track in iTunes, and select Get Info
The iTunes Summary window shows the location of the MP3 file.
13) To check the default location of the MP3 files you create in iTunes, click on the rectangle icon in iTunes upper-left corner, go to Preferences, and go to the Advanced Preferences tab.
You see iTunes Media folder location, and you can change it if needed.
Remark: iTunes does not suppress the .wav file when encoding its .mp3 version, so at the end of the operation, you get 2 audio tracks with the same name in iTunes library:
Honoree of a 2014 CES Innovations Award, Hercules DJControlWave’s Bluetooth® connectivity and rechargeable battery gives DJs complete freedom to mix and rock parties anywhere.
Las Vegas, January 7, 2014 - Hercules, a worldwide leader in audio and digital DJing, is proud to unveil the first wireless DJ controllers custom-designed for iPad® at CES Las Vegas.
Inspired by its sleek, wave-shaped design, the new controller is named the Hercules DJControlWave. This truly unique and innovative concept has also been recognized as an honoree of the highly coveted CES Innovations Design and Engineering Award 2014.
With its iPad® control via Bluetooth® wireless technology, total mobility thanks to its built-in rechargeable battery, and its futuristic design, the Hercules DJControlWave is the undisputed "new wave" DJ controller.
Complete mixing freedom There’s no need for any kind of cable between the controller and the iPad®: the Bluetooth® connection is instant and the control is totally wireless. When mixing at a party, the DJ is even free to take the iPad® onto the dance floor, away from the controller, without ever losing control of the mix! The Hercules DJControlWave’s range is up to 33 feet (10 meters).
The controller’s built-in rechargeable battery is also a huge plus in terms of freedom of movement: say goodbye to the days when a DJ always had to keep the controller connected to a power source. Battery life even allows for a whole night of non-stop mixing (up to 8 hours)!
DJs can either connect speakers to the iPad® via a wired connection or wirelessly if using a Bluetooth® speaker, making it possible to mix without any cables at all for the ultimate in DJing freedom!
The "new wave" DJ design: stylized and futuristic Extremely lightweight and showcasing an elegant look, the innovative design of the Hercules DJControlWave ripples like a wave, and is perfectly crafted to support the DJ’s iPad®. The iPad®’s angle of support can be adjusted in order to adapt to different DJing positions and styles. All controls are intuitive and ergonomic, including the two jog wheels, two pitch sliders, buttons for effects, samples and cue points, and rotary encoders for EQ settings.
Even the controller’s backlighting, which adds to its futuristic look, has been designed to be both attractive and helpful: it guides the DJ, even in low-light conditions.
DJUCEDTM DJW: the free, custom control app The DJUCEDTM DJW app has been specially designed for the Hercules DJControlWave, and was developed to function in perfect harmony with the controller (the app is available for free on the App Store). The app is incredibly simple both to learn and to use to create great mixes, even for those just starting out as DJs.
Multi-talented Although this new controller has been designed for the iPad® (its "Made for iPad" certification is pending), it is also compatible with both Mac® and PC, via a USB connection and the included DJUCEDTM 40° software.
The Hercules DJControlWave also comes bundled with a super-convenient splitter cable - allowing users to connect both speakers and headphones to privately preview upcoming tracks.
The Hercules DJControlWave will be available from spring 2014, at a suggested retail price of $299.99.
To check it out, come visit Hercules at CES Las Vegas, the Venetian Hotel, Veronese 2504 meeting room, from January 7 through 10, 2014.
