What are you listening to right now...a podcast, linear radio show, news or is it your latest earworm?
The digital age has revolutionised how people access and consume audio content, not to mention the content itself. But what are the latest trends in the audio sector? And what role does public service media (PSM) play in this transforming environment?
PSM have been a staple of the audio industry since the first radio show hit the airwaves. However, like in most other media industries, the digital revolution has brought new competitors, challenges and opportunities for PSM in the audio sector. This new report provides an overview of the current major trends in audio, as well as a deep dive into what PSM are doing in this sector.
iZotope has just completed a large piece of work to help put something back into the pro audio community. They have just has unveiled Pro Audio Essentials, which is a free game-based course for music producers, engineers, in fact anyone working with audio, to practice and improve their audio skills.
Pro Audio Essentials is a web-based educational experience and iZotope believe it is the first of its kind in the audio education space, offering an interesting combination of audio games, ear training, and instructional videos that help music makers in an interactive learning environment.
The course's interactive, game-based design helps users practice concepts even as they're having fun leveling up through audio challenges. Through regular practice, iZotope's aim is that 'players' will steadily improve their understanding of audio essentials like equalisation, compression, bit depth, and sample rate. Both beginners and the more experienced should reap noticeable benefits when recording, mixing, and mastering.
Pro Audio Essentials has been designed by mastering expert Jonathan Wyner who is iZotope's GRAMMY-nominated Director of Education, and reflects iZotope's deep-rooted passion for both education and empowerment. Jonathan told us...
The Xtreme Audio Essentials Gift Set includes a pair of Bluetooth Headphones, Earbuds and a Speaker. This is the perfect gift for music lovers by giving them the ability to enjoy their favorite music anytime, anywhere. The Portable Speaker has an LED accent ring and sleek alloy body with 33 feet of range and 3 hours of playtime. The over-ear Headphones boast high definition sound and an adjustable cushioned headband. Finally, the Magnetic Earbuds have built-in audio controls and a microphone for hands-free calling.
Essential Sound is an all-in-one panel that gives you an extensive toolset of mixing techniques and repair options. This feature is useful for your common audio mixing tasks. The panel provides simple controls to unify volume levels, repair sound, improve clarity, and add special effects that help your video projects sound like a professional audio engineer has mixed them. You can save the applied adjustments as presets for reuse, making them handy for more audio refinements.
Premiere Pro allows you to classify your audio clips as Dialogue, Music, SFX, or Ambience. You can also configure and apply presets to a set of clips that belong to the same type or to multiple clips.
Once you assign an audio type, for example Dialogue, for a voice-over clip, the Dialogue tab of the Essential Sound panel presents you several parameter groups. These groups allow you to carry out the common tasks that are associated with dialogue, such as unifying the different recordings to common loudness, reducing background noise, and adding compression and EQ. The audio types in the Essential Sound panel are mutually exclusive, that is, selecting one audio type for a clip reverts the previous changes done on that clip using another audio type.
All the changes that you do using the Essential Sound panel controls are reflected in the more advanced clip settings. For an effect like restoration or clarity, audio effects are inserted into the clip rack. If you are an advanced user, you can start with your primary edits in the Essential Sound panel and then go on with your sophisticated internal effect settings and apply finishing touches.
Improving the clarity of the dialogue track in your sequence has dependency on various factors. This is because of the variations in volume and frequency of the human voice that range between 50Hz and 2KHz and the contents of the other tracks that go with it. Some of the common methods used for improving dialogue audio clarity are compressing or expanding the dynamic range of the recording, adjusting the frequency response of the recording, and processing the enhancing male and female voices.
EQ: Reduce or boost selected frequencies in your recording. You can choose from a list of EQ presets that you can use on your audio and adjust the amount using the slider. To change the settings of EQ preset, select Effects>Audio Effects>Graphic Equalizer to view the graphic equalizer that you can adjust during playback, and save the changes.
Premiere Pro allows you to create artificial sound effects for your audio. SFX helps you create illusions such as the music originating from a particular position in the stereo field or an ambience of a room or field with appropriate reflections and reverberation.
OpenAL is the Core Audio implementation of the open-source OpenAL standard for positional audio. It is built on top of the system-supplied 3D Mixer audio unit. All applications can use OpenAL, although it is best suited for games development.
The AVFoundation framework (AVFoundation.framework) provides the AVAudioPlayer class, a streamlined and simple Objective-C interface for audio playback. It also provides the AVAudioEngine class for more sophisticated audio handling.
Core Audio uses the notion of proxy objects to represent such things as files, streams, audio players, and so on. When you want your application to work with an on-disk audio file, for example, the first step is to instantiate an audio file object of type AudioFileID. This object is declared as an opaque data structure in the AudioFile.h header file:
This sort of pattern is consistent throughout Core Audio, whether you are working with audio files, iPhone audio sessions (described in Audio Sessions: Cooperating with Core Audio), or even hardware devices.
In some cases, a property applies to an audio object as a whole. For example, to enable audio level metering in a playback audio queue object, you set the value of its kAudioQueueProperty_EnableLevelMetering property to true.
Implement the callback function. For example, you might implement the audio queue property listener callback to update the titles and the enabled/disabled state of buttons in your user interface, depending on whether an audio queue object is running or stopped.
In Core Audio, you use two universal data types to represent any audio data format. These types are the data structures AudioStreamBasicDescription (Listing 2-4) and AudioStreamPacketDescription (Listing 2-5), both declared in the CoreAudioTypes.h header file and described in Core Audio Data Types Reference.
In this structure, the mReserved member must always have a value of 0. Other members may have a value of 0 as well. For example, compressed audio formats use a varying number of bits per sample. For these formats, the value of the mBitsPerChannel member is 0.
The constants and data types used as values here are declared in the CoreAudioTypes.h header file and described in Core Audio Data Types Reference. Using the AudioUnitSampleType data type here (and the AudioSampleType data type when handling audio I/O) ensures that an ASBD is platform agnostic.
The previous chapter defined a packet as a collection of one or more frames. It is the smallest meaningful set of frames for a given audio data format. For this reason, it is the best unit of audio data to represent a unit of time in an audio file. Synchronization in Core Audio works by counting packets. You can use packets to calculate useful audio data buffer sizes, as shown in Listing 2-8.
To use VBR or VFR formats in Core Audio, you use the audio stream packet description structure (Listing 2-5). Each such structure describes a single packet in a sound file. To record or play a VBR or VFR sound file, you need an array of these structures, one for each packet in the file.
In CBR and VBR formats (that is, in all commonly used formats), the number of packets per second is fixed for a given audio file or stream. There is a useful implication here: the packetization implies a unit of time for the format. You can use packetization when calculating a practical audio data buffer size for your application. For example, the following method determines the number of packets to read to fill a buffer with a given duration of audio data:
To convert audio data from one format to another, you use an audio converter. You can make simple conversions such as changing sample rate or interleaving/deinterleaving. You can also perform complex conversions such as compressing or decompressing audio. Three types of conversions are available:
When you use Audio Queue Services (described in Recording and Playback using Audio Queue Services), you get the appropriate converter automatically. Audio Codec Services (Mac only) lets you create specialized audio codecs, such as for handling digital rights management (DRM) or proprietary audio formats. After you create a custom codec, you can use an audio converter to access and use it.
