Introduction
Welcome to the Korg AudioGate High Resolution Music Player.
AudioGate is an advanced music player and audio recorder, as well as a flexible file conversion application. Best of
all, AudioGate is fully compatible with 1-bit DSD audio. When Installed on your computer, AudioGate can play,
manage, and convert the format of your digital audio files so that you can enjoy hearing them reproduced with the
highest levels of clarity—including direct playback of 1-bit digital audio files. Combined with certified audio
devices—such as the Korg DS-DAC Series—AudioGate allows the direct recording of 1-bit audio data.
In addition, AudioGate allows projects or files created using the Korg MR Series of DSD 1-bit recorders, DS-DAC10R, or Nu I* to be converted into any audio file format you choose for export or to create an audio CD or DSD disc.
Convenient file-editing features including cut, fade, and normalize add professional edge to your finished product.
Please note that regardless of format, each audio element in an AudioGate Songlist is referred to as a Song.
*Nu I is sold only in Japan.

The Songlist
The Songlist section located in the lower half of the screen will display either information about the Songs (audio
files) registered in the AudioGate Library (see page 7), or the Songs in the currently selected Playlist (see page 10).
Click the Side bar Display button to open the Library/Playlist selection screen.
Master Volume/Input Level
The Master Volume/Input Level sliders can be adjusted by simply dragging them up and down.
Playback/Master Volume:
In addition to the playback Gain settings saved individually (see page 29) with each song, AudioGate offers an
adjustable Master Volume control for playback.
Recording/Input Level:
When the Korg DS-DAC-10R is connected, during recording (even when paused) and input monitoring this control
will determine the input level of the DS-DAC-10R.
Input Monitor Settings
Use the Input Monitor settings to set your input levels and to monitor the audio input as you record. Click the
Input Monitor Settings button when stopped to monitor the input device sound. Click the button again to cancel
setting the input monitor.
Peak/Level Meter and Clip Indicator
Player View:
During song playback and during export, the AudioGate Level Meter shows the peak values of the output data—
following any sample rate conversion.
Edit/Recording View:
When configuring the input monitor settings and when recording (including pause), the Level Meter shows the
level of the incoming audio signal. When using an Nu I or DS-DAC-10R and the phono equalizer for recording is
selected in the recording settings, the level of the signal after going through the phono equalizer will be shown.
When the incoming audio signal level is too high, clipping may occur and could adversely affect your sound. In this
case the Clip indicator will light, and you should re-adjust the input level, or adjust the output level of the audio
source. The clip indicator is only displayed in the Edit/Recording View.
5
Using the Peak/Clip Hold Function
The AudioGate level meter is equipped with a peak hold function and a clip indicator hold function. This feature
allows you to easily see the highest input level without constantly observing the meters. You can set hold duration
of peak and clip—the length of time displayed before reset—separately.
Here's how:
1. Right-click (Mac: Control + click) the level meter.
2. Choose [Peak Hold Duration of Level meter] or [Hold Duration of Clip Indicator] and select the desired time
from the options shown.
This function can also be accessed by clicking the Menu button and selecting [View] - [Peak Hold Duration of Level
meter] or [Hold Duration of Clip Indicator].
Clearing the Peak Hold and Clip Indicators Manually
Clicking on the level meter when it is in use will immediately clear the Peak Hold and Clip indicators.

Registering Files and Projects
drag & drop
In order for AudioGate to work with the audio files and MR projects (created using a KORG MR Series recorder)
saved on your computer, they must first be registered with the AudioGate Library.
Each registered item is referred to as a Song.
Registering a Song does not create a copy of the file in AudioGate. Instead, file information needed to work as
the Song in AudioGate is registered. Before you proceed, we recommend that projects recorded on your MR
Series unit be copied to the hard drive of your computer.
When many Songs are registered at a time, it will take time for them to appear in the Songlist. In addition, the
Song waveform display requires time to be analyzed during registration, so the Song waveform may also take a
while to appear.
Song Registration
Registering an MR project
When registering data that was created on a Korg MR Series digital recorder, it is possible to register just the audio
file. However, it is best practice to register the entire MR project. This way, AudioGate can also access any Marks
that were added during recording, and divided audio files will be automatically joined so that they can be handled
as a single Song.
• Drag the MR project (the entire MR project folder) that you want to register into the songlist.
Alternatively, you can click the Menu button and select [File] - [Add Audio Files...] and then choose the MR Project by selecting the .prj file from within the folder.
When the Library Songlist is displayed, the MR project is registered to the Library as songs.
When a Playlist is displayed, the MR project is registered to the selected Playlist as well as to the Library.
Simply registering an MR project in the AudioGate library does not create a backup of the file. We recommend
that you make a copy beforehand of projects recorded on a Korg MR Series to the hard disk of your computer.
7
Registering an Audio File
drag & drop
Audio files can be registered as Songs for use with AudioGate. Any file in one of the many formats which AudioGate supports can be imported and registered as a Song (see page 56).
• Drag the audio file that you want to register into the songlist.
Alternatively, you can simply click the Menu button and select [File] - [Add Audio Files...].
When the Library Songlist is displayed, the audio file is registered to the Library as songs.
When a Playlist is displayed, the audio file is registered to the selected Playlist as well as to the Library.
When the Library Songlist is displayed, you cannot register a Song that has already been registered. You are
ignored when it drag-and-drop.
Registering an iTunes Song
Your iTunes songs can also be registered into the AudioGate Library.
1. Click the menu button to select [File] - [Add iTunes songs].
2. The selected iTunes song(s) is now registered into the Library.
Your iTunes songs will only be registered into the AudioGate Library when they are selected using the procedure described above [Add iTunes songs]. A Song already registered in the library will not registered in duplicate.
Registering a new Recording
When recording using AudioGate, as soon as recording has stopped, the new recording will be automatically registered into the AudioGate Library as well as into the current Playlist.

Playlist. Export and Burn Disc can be chosen as well. For more information on the other choices see page 38 (Export)
and/or page 46 (Burn Disc).
Removing the Playlist deletes the registered information of the Songs in the selected Playlist only. These same
Songs will remain registered in the Library Songlist and in any other Playlists in which they appear.

Device. This is also where the recording input device and sample rate parameters are set.
A fast CPU is required for stable playback of 1-bit audio files directly, or real-time conversion from PCM to 1-bit
audio files. If any skip or noise occurs frequently during playback, adjusting the buffer size may help improve
the performance. To avoid errors due to CPU overload during recording, we recommend that you set this to the
maximum value.
This is where input devices and the sample rate to be used for recording are set.
