PC-FLS8 Flashlog Audio & Radio Capture Logging Software
Flashlog 8 is configurable, ultra powerful multi-channel logging software. It makes use of separate Sonifex hardware (sound and radio capture cards) to provide a host of logging features on a single PC platform.
It can record from analogue and digital line inputs, IP based line inputs (Axia™, Wheatstone™ or Dante™), from the Sonifex radio capture cards and internet radio streams.
Up to 2 years of radio broadcasts or audio can be logged, depending on available hardware.
When also using the Sonifex PC-DAB DAB+ multi-ensemble PCIe Radcap card, the software records the entire contents of up to four ensembles. Decoding occurs during playback, showing DLS text, MOT slide shows and electronic programme guides along with the audio.
- Analogue, AES-3, Axia Livewire™, Wheatstone Wheatnet™ & Audinate Dante™ IP line inputs supported (Note separate proprietary drivers needed from the IP audio suppliers).
- Up to 64 stereo inputs supported, each reconfigurable as a pair of mono inputs.
- Up to four assignable line sub-categories for grouping channels.
- Selectable audio compression rates ranging from 80kbps to lossless.
- Adjustable no. of logging days per input.
- Recording time of up to two years, settable on each channel or ensemble (dependent on no. of channels, audio compression rate & HDD size).
- Operates on 64-bit Microsoft Windows™ 7/8.1/10 Professional operating system.
- Network playback using free Flashback 8 application (also compatible with Flashlog 5, 6 and 7 recorders).
- SNMP monitoring and alarms, including RDS / DLS text.
- Optional skimming control inputs supported.
- Live input monitoring on logger unit.
- Selectable audio failure alarms.

But DAB+ isn’t all you get with Flashlog 8. By using suitable hardware, Flashlog 8 has the ability to record up to 64 stereo line channels, 32 stereo FM stations, 32 AM stations, 4 DAB+ ensembles and 32 internet radio streams, limited only by the number of PCIe slots on the motherboard that you use. (See later for the PC-RACK units that can be used with Flashlog 8 software).
The number of HDD logging days can be independently set for each line, AM or FM channel, and for each DAB+ ensemble. Archiving also allows parallel recording of selected channels to a permanent archive location on the network, either continuously or on selected days and time ranges.
All text fields are Unicode-based, allowing multilingual display and entry.
Playback on both the logger and through Flashback 8 supports saving log extracts as MP3 as well as WAV, WMA and AVI files.
The Flashlog 8 recorder runs as a Windows service and is controlled from under the Sources tab in the Flashlog application.
Each line source can be configured as Stereo, 2 x Mono, 1 x Mono or Hidden. When set to Hidden, the input is still being recorded, but the source doesn’t appear on the playback screen. The number of recording days drop-down list is dynamically populated to ensure the hard drive space won’t be exceeded. If line channel subcategories have been created, the subcategory can also be selected from a dropdown list. Each input can have a 12-character name, which is what appears on the playback button for that channel, and when 2 x Mono mode is selected, separate names are given to each channel. The audio compression rate can be set to 80kbps, 128kbps, 256kbps or lossless, and audio failure alarms can optionally be enabled.
When used with the PC-AM and PC-FM radio capure cards, AM and FM radio capture sources are shown next, with edit fields for the frequency and an optional descriptive name. If RDS is present and no descriptive name has been entered, the transmitted station name is used and is dynamically updated should it be changed by the station. RF and audio signal levels are shown, along with stereo and RDS indicator lights for FM channels. Alarms (audio or carrier fail) can be optionally enabled. A drop-down list allows the number of logging days to be set, with the range determined dynamically from the available drive space.
When using the PC-DAB radio capture card, each DAB ensemble has a spectrum display, an RF level indicator, a phase reference correlator level, an uncorrected error count and an alarm enable checkbox. When alarms are enabled, the Configure button opens a dialog box allowing alarms to be enabled or disabled on individual services. The number of logging days for each ensemble is set from a drop-down list.
Finally shown are the internet radio streams displaying the URL, stream status, bit-rate, audio coding and audio levels, with drop-down lists for setting logging days and alarm enable checkboxes. Audio level meters, based on analysing the compressed audio data, are also presented.
Additional buttons at the bottom of the Sources window provide further source and SNMP configuration.
The playback screen, available under the Player tab on the Flashlog unit and in the free Flashback network playback application, provides easy selection of audio source and playback date and time.
Across the top, tabs for each source category or subcategory select a group of up to 32 buttons, identified by the channel name. In the case of DAB sources, the broadcast short service name is used.
The waveform display can span one minute, ten minutes, an hour or a day, by using ‘span’ buttons. The date is selected from a calendar control, with the time set either by using the up and down buttons or by directly typing into the hours, minutes and seconds fields. The playback position can also be adjusted by dragging on the ruler bar below the waveform.
A section of audio can be marked either with the mouse in the waveform window or by navigating to the start and end points and clicking on the Mark button. Once highlighted, the section can be saved to the Windows clipboard or to a file in WAV, WMA or MP3 format. For DAB channels, an AVI video file incorporating the slideshow and DLS text along with the audio can also be created.
The display window on the lower left shows DLS text for DAB services, RDS radiotext for FM stations and artist/title metadata for internet streams. The window on the lower right shows skimming events for line channels, slideshows for DAB audio services, a program guide tree view for DAB EPG services and header information for internet streams.
Flashback can be simultaneously used on multiple workstations, up to the limit imposed by the recorder’s operating system (20 users for Windows 7/8/10 or the number of installed CALs for server versions).
