Installation – Player Program

You can easily install the Player program on the AudioFile Server or any remote machine.


Setup Files

Copy the Player files package to a folder titled “LoggerPlayer” on any machine with LAN, WAN, or Internet access to the logging machine.


Connect to Logger Machine

Open the player program and select the “Connect” button to open the connection dialogue. Enter the name or I.P. address or “machine name” of the AudioFile Server, and login/password. When numberous AudioFile servers will be accessed, include a brief description of it for future reference.

NOTE: There should be a sub-directory (folder) named “AudioLogger”. A shortcut to the player can be placed in the taskbar or on the desktop for convenience.

KLZ AudioFile™ Player Program

AudioFile Player or “AudioFile” is used by people to access the server and it’s resources. The player operate in three modes; “Monitor”, “Skim” and “Archive” (logger). Preview incoming sources, audio segment playback, and file extraction with the AudioFileTM player program. This program connects to an AudioFile Server by TCP/IP by LAN, WAN, or a common Internet connection. Users login then navigate the system as required.


Navigating The Toolbar

The menu located at the top of the interface are for general program features, adjusting the Time-Line scale (zoom), and manipulating the display windows. Notice that additional menus appear as different Player types are opened. For example, while monitoring, a “compression factor” lets the user choose what MP3 bit-rate they’d like to hear. Lower bit-rates are best for Internet access or remote streaming.


Using the Player Program

     To begin, open the Player program and click on the “Connect” button.

In the dialogue that appears, select the AudioFile system of interest. Enter its machine name or I.P. address if not previously connected. The Adress will be retained by the dialog.

There are two passwords defined in the configuration dialog; one for Administrator(s), another for general user access. In reality, only the password is required for general users. We encourage users to enter their name here... (and, it may be handy if this were logged in the future?)

In applications such as audio logging, technical staff is often called upon for audio log copy. With AudioFile, PDs, managers, traffic and sales people can all access station audio logs without interrupting engineering staff.

Near Real Time Audio Monitoring

To monitor an incoming audio channel live, highlight a channel in the tree on the left of the player, open a new player window, and select the “Monitor” button. The player will start a near real-time playback of the selected channel. The audio heard is an MP3 stream being encoded on the fly by the AudioFile Server.

While monitoring you can choose other sources by simply clicking on another channel title in the navigation tree. The player automatically switches to the desired channel source. As well, you may open additional players and monitor multiple channels at once.


Note: We call the feature “Near Real-Time Monitoring” because the audio heard is after writing to disk and MP3 encoding at the selected playback stream rate. The delay is typically less than a few seconds depending on the IP connection being used.

(i.e. directly over a LAN, over a Corporate WAN, VPN, Internet, etc)

Connect by machine name or IP address: Administrators require Name and Password. Others use a generic password.

Playing Archived Audio (audio logger)

To play a specific station log, click on the channel of interest in the Navigation Tree. Now open an audio player using the “New Player” button at the top of the screen, or right-click in the tree area and select “New Player”, or in the Logger menu. Press “Play” to start the audible playback from the start of the selected day/date. Click on any position in theThe TimeBar to hear the audio archive at that time.

Clicking anywhere in the time-bar will re-cue the audio player to the newly selected time. Use the zoom controls or “zoom menu” to make it easier to locate a very specific moment. At the highest zoom level, easily locate a time down to the second.

To extract a specific portion of an audio log , In-Point and Out-Point markers must be set. In either order; click your mouse at the point in the Time-Bar where your segment will start and click “Set In-Point”, then do the same at the time where your selection should end and click on “Set Out-Point. Press Play to hear the selection, or Extract to save the selection as an MP3 file.


Navigating The Time-Line – Locating Specific Times

The graphical timeline across the top of the screen is used to navigate within an Archive or “audio- log”. Active audio recording is shown as a solid green bar. Gaps or interruptions in the green bar indicate there was no audio being recorded on the selected channel for that period. In most cases, the green bar should always be continuous.

Use the Time-Line Slider to quickly navigate to any time you wish. The Zoom In / Zoom Out buttons in the toolbar above will adjust the TimeLine’s scale as desired, down to 1sec. resolution. Click at any point in the timeline and press play to hear the audio recorded at that time.

If the player has been left running a long time, the playback position may be “off screen”. To quickly re-position to the time point where the cursor resides, simply click the “Find Cursor” button in the toolbar. The screen will refresh with the cursor point located in the viewable area.

Channel / Archive Tree - Navigating in AudioFile Player

The Channel / Archive tree makes it very easy for users to find the desired audio segments. Clicking on the channel name enables monitoring, expanding to dates which resemble the folder system found in many computer applications.

Navigate the Archive Tree by either: 1. Click on the + icons to expand (show) the channel view to include year/month/week/day sub-folders, Click the - to collapse (hide) the folder view. 2. Double-clicking the folder title will also expand/collapse the tree as desired.


Note: The Channel / Archive Tree only displays days that contain captured audio. If a day is not present for a specific channel, no audio was captured for that channel on that day.

Extracting Audio as MP3 Files

To save a portion of an archive as an MP3 file, set In and Out-point markers and click the “Extract” button on the player. The “Extract” dialogue (shown left) will open.

Change settings in the dialogue as desired for your extracted file(s):

❑ In the “Extract To” entry field, enter a

folder name or browse [...] to the folder where you will save the extracted file(s). ❑ Check all sub-folders to be included when the system creates the storage folder. ❑ In the “Channel ” entry field, designate the reference name of the folder for the extracted files to be kept in. By default, the channel name is inserted here. You may accept or modify this as desired. ❑ Set the “Maximum File Duration” to the

largest size clip size you wish the files to be. When audio to be extracted exceeds the maximum duration, the program creates multiple sequential clips as required.

Note: Maximum File Duration is 4 hrs. ❑ “Overlap Split Files” adds a portion of the

previous file for audible verification of the integrity where files are split.

Note: Overlap maximum is 30 seconds.

By default, extraction creates 64kbs MP3 files in a folder appended into subfolders resembling the navigation tree in AudioFile. Sub-folders including; channel, date/time stamp, sequential order ID, and the file name you entered in the previous dialogue will result if all “append” options are selected.

The extracted clips can be played using any device capable of playing MP3 files. With software such as Windows Media Player®, simply drag all extracted files onto the play-list. The naming convention of the extracted files can be used to easily list the flies in correct order.
