Audio Utility

The Audio Utility allows the user to change or analyze multiple assets in Zetta. Using the Launch Audio Utility button from the Library toolbar the user can open the Audio Utility window. The left side of this window shows a list of the assets that were selected in the Library module. The right side of this window shows the Actions that can be taken for the selected assets. The Actions in this window will vary based on the asset type, asset scope and GSelector Integration.

Mass Changer

Active - The Active utility allows the user to easily activate multiple songs at once for one station or all stations. See the Activate Multiple Audio Assets section of this guide for more information.

Approval - When the Audio needs approval before airing Station configuration option is checked this utility becomes available, this utility makes approving audio assets for On-air play quick and easy. This utility can also be used to change the status of an asset to Waiting for Approval or Disapproved. See the Approving Assets for On-Air Play section of this guide for more information.

Add/Change Category - The Category utility is available when selecting Songs, Link or custom Asset Types for a specific station. This utility allows the user to set or change the Category of these Assets.

Start Date/Hour – The Start Date/hour fields are used to specify when the assets will be available for play. Use the calendar control to select a date then adjust the time as needed. Use the Clear Date checkbox to remove the Start Date/Hour values from the selected assets.

End Date/Hour – The End Date/Hour fields are used to specify when the assets will no longer be available for play. Use the calendar control to select a date then adjust the time as needed. Use the Clear Date checkbox to remove the End Date/Hour values from the selected assets.

Hour Restriction - The Hour Restriction option can be used to assign an Hour Restriction Grid to the selected assets for the current station. This option is only available if a station is selected in the Library Module.

Split Behavior - The Split Behavior option is available when the Splits feature is enabled in the System Configuration | General tab. Use the Split Behavior drop-down to select the desired behavior when the Asset is scheduled in the Log.

Kill Date - The Kill Date is the date to stop scheduling the asset and automatically delete it from the Library. Use the Clear Date checkbox to remove the Kill Date value from the selected assets.

Assign to Station Group - This option is available when assets with a Cuts metadata Scope are selected. This option is used to assign a defined Station Group to multiple assets.

Assign To Station - This option is available when assets with a Cuts metadata Scope are selected. This option is used to assign a station to multiple assets.

Utilities

Change Asset Type - The Change Asset Type option is used to Move or Copy assets from one asset type to another. This utility is usefully when changing multiple assets to a different asset type. This option is only available for those assets that are NOT integrated with GSelector. When the selected assets are integrated with GSelector this option is changed to Copy to Asset Type.

Copy To Asset Type - This option is visible if the selected assets are integrated with GSelector (Song and Links). This option is used to Copy the selected assets to another asset type.

Export Asset - The Export Assets utility allows the user to easily export the selected assets to a connected drive. This can be used for backing up the assets or exporting a spot for a customer. Use the Export | File Drop setting in the Audio Format tab in the System configuration to set the format the audio to be exported. Once the user clicks the Go! button the user will be prompted for a location to export the audio assets. Each file that is exported will include the Cart Chunk (trim in/out; intro1,2,3; Segue; Hook In/Out) data for the audio.

Convert Audio - The user can convert any audio asset in Zetta to the configured Audio Format desired using the Convert Audio option in the Audio Utility. Convert Audio uses AFC to convert the audio.

Marks Analysis – The user can choose a single piece of audio or multiple pieces of audio to analyze the audio based on the Marks Analysis Settings configured in Configuration | System | Audio Processing tab.

Full Analysis –The Full Analysis runs through the selected file(s) to determine the gain values for all the supported algorithms in Zetta. Zetta then saves these values to the database to use based on the normalization selected for each station in Configuration | Station | Audio Processing | Normalization Settings. This option is also used to create a unique File Checksum hash value and Waveforms for each file selected, the File Checksum value is used when comparing like files received from a ZCast transfer or import into the system.

Update Zetta Activations per GSelector - The user can choose a single piece of audio or multiple pieces of audio to updated Zetta per GSelector.

Audio Utility Step-by-Step Topics

The Audio Utility allows the user to analyze, normalize and/or Convert existing audio in Zetta.

Marks Analysis

1. From the Modules Menu, click Library.
2. Highlight the desired audio.
3. Click the Launch Audio Utility button.
   
4. In the Utilities section select Marks Analysis.
5. Click Go!

Full Analysis

1. In the Configuration Menu, click Stations.
2. Select the station to set the normalize values.
3. Select the preferred Normalization Options as defined below:
4. Normalization algorithms used by Zetta:
   Limit Peak – When the Limit Peak option is check the Absolute Peak will be at 0dB
   Absolute Peak – (As used in AFC 4.0) Absolute peak normalization checks every sample in the audio file and calculates the largest audio peak value. (Default is –3dB)
   Root Mean Square – (As used in Selector/MC 15) Uses the square root mean algorithm to calculate peak values, which is the square root of the mean or middle of the squares of the values. (Default is –20dB)
   Filtered Peak – (As used in AFC 3.0) Filtered peak normalization analyzes all the samples within an audio file and calculates the peak level by ignoring 5% of highest samples. (Default is –6dB)
   Average Peak – Average peak normalization which is new with Zetta, analyzes all the samples within an audio file and calculates the median or middle value of the top 5% of the peaks. (Default is –6dB)
   Loudness (EBU R128) ITU-R BS.1770rev0 - Loudness normalization is concerned with balancing audio according to their actually perceived loudness. The EBU R128 is the recommended level of loudness at -23LUFS. The ITU-R BS.1770 standards provide an algorithm for quantifying the loudness and loudness level of a given audio asset in loudness units (LU or LUFS).
   Loudness (Gated) ITU-R BS.1770rev3 - Loudness (Gated) ITU-R BS.1770rev3 is an algorithm to measure audio loudness of a Gated block of audio. This is the default setting and is recommended for Broadcast audio.
