SIP codecs exploit compatibility

Radio World
3 years 2 months ago

Radio World Buyer’s Guide articles are intended to help readers understand why their colleagues chose particular products to solve various technical situations. This month’s articles focus on products for radio remotes and sports.

Kevin Leach is on location in the Yorkshire Pennines in Northern England, using a USB SIP Codec and Mediaport Sonja router.

In:Quality, a U.K.-based company that specializes in remote broadcast products and services, recently introduced the USB SIP Codec. Kevin Leach is founding director.

Radio World: What are the advantages of a SIP codec over other platforms?

Kevin Leach: The beauty of SIP is compatibility, now that so many devices support both SIP and the Opus audio format.

The person making a call from one compatible device doesn’t need to know anything about the equipment at the other end. They just dial its SIP address, and the call parameters are negotiated automatically.

RW: Can you give examples how your clients are using it creatively?

Leach: Sure. The touchscreen version of our USB SIP Codec has been extremely popular in parts of the BBC, and for Radio France. Both had to respond quickly to the first COVID lockdowns and were able to deploy our devices to their hosts and pundits, to allow them to connect to the studios from home.

The low cost and immediate availability of our devices allowed both broadcasters to purchase in bulk and at short notice. Meanwhile, the simplicity of the setup and on-screen controls allowed the hosts to install the codecs, without the help of an engineer.

RW: Are there misconceptions you’d like to dispel about the product or SIP in general?

Leach: I think some radio producers are still skeptical about SIP, and IP in general, because they have had bad experiences in the early days, especially when using bad WiFi or 3G connections.

Consumer broadband has become much more robust in recent years, especially when WiFi is eliminated. For that reason, our devices do not support WiFi, and instead are hard-wired to the router using Ethernet.

Because SIP is a telephony standard, many users are also surprised at just how clean the audio sounds with Opus, and how stable the calls are with our codecs, despite the lack of a delay.

RW: What else should we know?

Leach: Since the success of the USB SIP Codec, we’ve released a version that has built-in analog XLR connectors. These units are really versatile when hooked up to an analog board in a studio. You can send a link to guests who can connect in from a web browser, and you can even make and receive phone calls, if you subscribe to the extra functionality.

So in total our SIP codecs come in four flavors: USB SIP Codec Zero, a small device with no screen; USB SIP Codec Touch, with a 7-inch screen for use with USB mics; and the XLR versions of Zero and Touch. Separately, our ipDTL works similarly but runs in a web browser on a computer, while hybrIP is a version of ipDTL designed for talk show calls.

Radio World
3 years 2 months ago

PreSonus has introduced its new Revelator Dynamic USB vocal microphone and Revelator io44 audio interface.

The Revelator Dynamic uses the same custom-built, dynamic microphone capsule as the PD-70 broadcast microphone, and also offers presets intended to aid recording, live streaming, and podcasting.

Meanwhile, the Revelator io44 is a compact, four-in/two-out audio  interface that is bus-powered via aUSB-C compatible jack. The unit is intended for mobile recording as well streaming, and features a combo mic/instrument input with a XMAX-L mic preamp, as well as a ⅛-inch line-level stereo input for DJ mixers and mobile devices. A ⅛-inch stereo headphone output works with regular headphones and TRRS gaming headsets (mic in, stereo out). Balanced ¼-inch stereo main outputs are provided to connect to professional studio monitors.

[Check Out More Products at Radio World’s Products Section]

Revelator-series USB microphones and audio interfaces provide onboard signal processing, with the same Fat Channel EQ, compressor, gate, and limiter algorithms found in PreSonus’ StudioLive Series III mixers, plus reverb and voice effects like delay, vocoder, and more. Additional presets emulate concert halls, AM radio, robotic voices, and more. PreSonus’ UC Surface software for macOS and Windows provides access to the processor settings, allowing users to create their own unique sound and save them as presets for instant access.

Each Revelator comes with PreSonus’ Studio One Artist production and recording software for macOS and Windows. The Studio Magic software suite is also included with various effects, instruments, sounds and more. The Revelator Dynamic USB microphone also includes an extendable desktop mic stand.

The Dynamic USB microphone and io44 USB audio interface are available immediately at street prices of $199.95 and $179.95, respectively.

LinkUp Chooses IDC MAP System

Radio World
3 years 2 months ago

International Datacasting Corp. said it was picked by LinkUp Communications Corp. to provide a migration path for radio networks that use legacy ABR satellite receivers originally made by ComStream, Radyne, Comtech and IDC.

“While these units enjoyed widespread industry acceptance and ran reliably for over 30 years, they reached end-of-support several years ago,” IDC said in an announcement.

It said LinkUp is providing a replacement technology package based on the IDC MAP system, as well as installation and configuration services.

MAP Pro Audio Receiver Front and Rear Panels

The distribution package features the MAP line of audio products made by IDC. It said its systems offer “a simple, flexible and cost-effective upgrade path.”

IDC is owned by Novra Technologies Inc. The announcement was made by Gary Carter, VP business development and products for Novra Group/IDC, and Mark Johnson, president of LinkUp Communications.

“For networks looking for a turnkey service to streamline and outsource their uplink operations, LinkUp offers a hosted service based on the IDC MAP system from their newly acquired teleport in Denver,” IDC noted.

Russian Broadcasters Leave EBU

Radio World
3 years 2 months ago

Russia’s State Television and Radio Broadcasting Co. (VGTRK), Channel One and the Ostankino radio house have pulled out of the European Broadcasting Union effective today, Feb. 26.

The move comes after the EBU Executive Board’s decision on Feb. 25 to bar Russian acts from participating in the 2022 Eurovision Song Contest. That decision was in response to Russia’s invasion of Ukraine on Feb. 24.

According to the EBU’s statement, “The decision reflects concern that, in light of the unprecedented crisis in Ukraine, the inclusion of a Russian entry in this year’s Contest would bring the competition into disrepute.”

The recommendation to bar Russia from Eurovision came from the EBU’s Reference Group and was supported by its Television Committee.

[See Our Global News Page]

According to a report from the Russian news service TASS, the broadcasters said their exit from the EBU was “a response measure” to what “we view as an improper political sacrifice at the music forum which has always emphasized its non-political status.”

The EBU emphasized that it “consulted widely” among its membership before making the decision, and reaffirmed its apolitical goal of upholding the values of public-service broadcasting.

“We remain dedicated to protecting the values of a cultural competition which promotes international exchange and understanding, brings audiences together, celebrates diversity through music and unites Europe on one stage,” the EBU stated.

Eurovision 2022 is scheduled for May 10–14 in Turin, Italy.

VGTRK joined the EBU in 1993, followed by Channel One in 1995 and Ostankino in 1996. Russia first participated in Eurovision in 1994. In 2008, the Russian entry, “Believe” by Dima Bilan, won the contest.

A Simple Streaming Glossary

Radio World
3 years 2 months ago

A recent Radio World ebook explores the world of streaming for radio. In this excerpt David Bialik lays out some commonly heard terms.

The following may help you navigate the language around streaming. It is not intended to be comprehensive but to give you a head start in this growing medium with new technology emerging daily.

  • AAC — Audio Coding, an audio coding format for lossy digital audio compression. Usually preferred Advanced over MP3, it promises comparable or better quality at lower bitrates. AAC has been standardized by ISO and IEC as part of the MPEG-2 and MPEG-4 specifications.
  • Ad Delivery Network — An on-demand file serving network that can deliver commercial content for the streamer.
  • Ad Replacement — When ads broadcast over the air are replaced with different content on the stream.
  • AES TD1004 — The Audio Engineering Society’s Recommendation for Loudness of Audio Streaming and Network File Playback. These recommendations primarily are intended for “radio-like” mono and stereo streams.
  • Bitrate — Bitrate = Sample rate X bits per sample used to encode the music. The number of bits per sample also depends on the number of audio channels.
  • CDN — Content Delivery Network, a scalable distributer of streams.
  • Client-Side Ad Insertion (CSAI) — Advertising that only happens within the website or app streaming your content. Banners, video pre-rolls, other items specific to a player or page.
  • CMAF — A container format (see below).
  • Codec — Digital audio compression algorithm used.
  • Container Format — Otherwise known as a wrapper, this may contain the audio and video plus all the associated metadata (i,e. MP4, CMAF). The container carries the payload (audio, video, or data files).
  • Cuepoint — A marker residing in the metadata, triggering a new action.
  • Decoder — A component that is part of the player, used to reassemble the content.
  • Direct Ad Insertion (DAI) — Personalized ad replacement that is unique to the listener. This can be based on listener location, browsing preferences, etc.
  • Encoder — The system used to take the content and send it to the stream, usually by compressing your linear audio into an MP3 or AAC stream.

[Check Out More of Radio World’s Ebooks Here]

  • Encoding Format — The method of converting to a digital format (i.e., AAC, MP3)
  • FLAC — Free Lossless Audio Codec, a compressed audio format with no loss of quality.
  • FLV — Flash Video Format, a container file format used to deliver digital video content over the internet via Adobe Flash Player.
  • HE-AAC / HE-AAC v2 / AAC+ — “High-Efficiency AAC,” a lossy audio codec for low bit rate streaming, expanding on the quality vs. size gains made by standard AAC.
  • HLS — HTML Live Streaming, a high-quality transport format used by Apple.
  • Icecast — A streaming media project released as free software, maintained by the Xiph.org Foundation.
  • ID3 or ID3 tag — A metadata format that stores information (Title, Artist, etc.). This may be called the data container.
  • Injected content — Content from another source, usually replacing other content.
  • Interstitial — One or more recorded elements used in stream production (i.e., bumpers, jingles, promos, etc.)
  • LKFS — “Loudness, K-weighted, relative to full scale.” A standard loudness measurement. Sometimes referred as LUFS.
  • Lossless Streams — A high-bitrate non-compressed stream.
  • Lossy Streams — Digitally compressed sampled streams (i.e., MP3/AAC).
  • LUFS — “Loudness units relative to full scale,” synonymous with LKFS.
  • Metadata — The data stream that accompanies the media content. This can hold the “Now Playing” information, commercial cues, time code or any other information needed to play the stream.
  • MP3 — An audio coding format for lossy digital audio compression developed by Fraunhofer and Bell Labs. This supports very low bit rates.
  • MP4 — One of the earliest digital video file formats. Can be used for high-quality video or audio while maintaining relatively small file sizes.
  • MPEG-DASH — Dynamic Adaptive Streaming over HTTP, an adaptive bitrate streaming technique that allows for high quality of content. This is comparable to HLS.
  • Now Playing Information — “What the stream is playing” can be displayed, usually sent by metadata.
  • Ogg — A container format.
  • Ogg Vorbis — An audio coding format with lossy audio compression.
  • Player — The program used on the audience side to play the content; it could be an app.
  • Podcast — A digital audio file that can be downloaded to a personal device and/or player.
  • RTMP — Real Time Messaging Protocol, a TCP-based protocol that maintains persistent connections and also allows communication with low latency. This allows for a stream to be delivered correctly.
  • Server-Side Ad Insertion (SSAI) — Advertising added to audio as it is streamed or delivered, rather than from the studio playout. Ads become part of the audio itself.
  • Shoutcast — A software application that allows anyone to stream audio over the internet.
  • Total Line Reporting — When the stream and over-the-air product are the same and no segments are substituted.
  • Transport Format — How the stream is delivered (e.g. HLS, Icecast, rtmp)
  • xHE-AAC — A lossy audio codec for low bit rate streaming. It also is used by Digital Radio Mondiale (DRM).

David Bialik is a consultant; co-chair of the AES Technical Committee for Broadcast and Online Delivery; and chair of the Metadata Usage Working Group at the NRSC. He is former director of stream operations for CBS Radio and Entercom.
