Formerly known as Sample Manager, Myriad from Audiofile Engineering is a fully featured batch converter for audio files, providing a useful toolkit both for sample library creation and for broader applications in just about every corner of the audio world. It includes a comprehensive library of processes or ‘Actions’ that can be imposed on multiple files, as well as the ability to customise and save your own edited Actions. Enhancements in the latest version 4 include speed and stability improvements, as well as an expanded feature set. Output formats supported include AIFF, WAV, Broadcast WAV, ACID, CAF (including PCM, ALAC and AAC encoding), Ogg Vorbis, VOX, Apple Loops, µLaw, Apple Lossless and FLAC, while on the input side, pretty much any common audio file format is recognised including MP3 and other compressed formats.
Go With The Flow
Myriad has a streamlined look that, thankfully, doesn’t follow the current trend for making everything black or dark grey! The GUI is airy and uncluttered, and is composed of two windows: the Main window, and a Waveform window that can be opened or closed from the Window menu or using a key command. This latter window is used to define areas to be trimmed, snipped, or played back for auditioning. If beat extraction is being applied, the detected beats are also shown on the waveform display. The Main window shows the Files List, a smaller Waveform Overview and the Workspace. Files to be processed are simply dragged into the left-hand section of the window, where they are automatically analysed by Myriad in readiness for processing.
The operating procedure is to drag in the files you wish to process, then to arrange various Actions to create a ‘Workflow’. The Workflow is then run, and new processed files generated. In the main, this is all drag-and-drop simple. Actions that can be performed are listed by function, so that you see anything relating to gain (such as normalising, fades, gain change) in one menu section, file attributes in another, and so on. A view filter allows you to look only at the Actions you are interested in, and all processes apart from compression can be previewed before you commit. For musical samples, the MIDI base note can automatically be detected and added to sample attributes, and files can be trimmed in length and have fades applied. Beat extraction is another of the useful sample-processing options available.

The Workspace, to the right of the main screen, has three view options selected using the Details, Process or Activity buttons; another button flips between All Files and Selected Files. The currently selected audio file is shown in the small waveform window at the top right, and file info for any selected file can be shown by clicking the ‘i’ button at the bottom right of the Files area. Selecting Details shows a comprehensive list of file attributes that includes positive and negative peak values, RMS level, Average level, Form Factor, Crest Factor, number of clipping events, separate Mid and Sides peak values and Program Loudness in LUFs.
Action Stations
In Process view, Actions are added to the Workflow list either by double-clicking or dragging them to the right-hand panel, where they can be reordered as required. The Actions List shows all the Myriad standard Actions plus any custom User Actions, which include the option to process via a selected Audio Units plug-in — if, for instance, you need a compressor that can be adjusted in greater detail than the built-in one, or one that has gain-reduction metering, the best option is to use a third-party AU plug-in and to incorporate that in your Workflow.
There are over 100 Actions in the standard library, most of which have user-adjustable parameters; adjusted versions of the standard Actions can be saved as User Actions by dragging the renamed, modified version back into the Actions List. Each Action displays a green circle with an ‘i’ inside it: clicking this displays more details on what each Action does. Actions you use on a regular basis can be marked as favourites, and it is also possible to back up your Workflows using the Export Workflow menu command.
The Waveform window comes into its own when a detailed focus on the audio is needed.
File names and attributes can be changed, and there’s the option to keep the original files or to have the processed versions replace them. There’s also the option to set up a new destination folder for your files if the default doesn’t suit you. Processing includes the respected Goodhertz Good Dither and sample-rate conversion algorithms, and there’s AppleScript support. Myriad supports Constant, Average and Variable MP3 bit-rate options and can be set to apply the same Action to all files or individual Actions to specific files. There’s also support for Broadcast WAV metadata. If you simply want to sample-rate-convert a batch of files or de-interleave stereo interleaved files, Myriad will do it for you, and it will happily convert the file format at the same time. Additional Actions can include sending files to iTunes, DropBox and SoundCloud.
Once you’ve set up a Workflow, you just need to click the Run Workflow button and let Myriad get on with the job. In my tests I set up a new folder to receive the processed files and opted to keep the originals intact. As each file is processed, information may be displayed in Activity views including (hopefully) a ‘no errors’ message, but if a corrupted file is encountered it will be skipped and logged rather than holding up the whole process.
In Conclusion
The sheer number of Actions that can be performed on a file makes Myriad a very powerful piece of software, but the designers have done a commendable job of making its operation really simple. Not only that, but the results are first-rate too. It is worth checking out Audiofile’s web site to discover the full list of Actions, as there are too many to list within a review. Myriad really does do just what it says on the packet, and will be an asset to just about any Mac user working with audio files. In fact, the only small thing about it is the price!
Alternatives
Perhaps the most obvious Mac alternative is Audio Ease’s established Barbabatch, though this is considerably more expensive than Myriad.
Pros
- Very easy to use.
- High-quality processing.
- Broad range of processing Actions.
- AU plug-ins can be added to Workflows.
Summary
Despite its modest cost, Myriad is a very useful tool that can save huge amounts of time when you need to process multiple files.

Computerized batch processing is the running of 'jobs that can run without end user interaction, or can be scheduled to run as resources permit.'[1]
History[edit]
The term 'batch processing' originates in the traditional classification of methods of production as job production (one-off production), batch production (production of a 'batch' of multiple items at once, one stage at a time), and flow production (mass production, all stages in process at once).
Early history[edit]
Early computers were capable of running only one program at a time. Each user had sole control of the machine for a scheduled period of time. They would arrive at the computer with program and data, often on punched paper cards and magnetic or paper tape, and would load their program, run and debug it, and carry off their output when done.
As computers became faster the setup and takedown time became a larger percentage of available computer time. Programs called monitors, the forerunners of operating systems, were developed which could process a series, or 'batch', of programs, often from magnetic tape prepared offline. The monitor would be loaded into the computer and run the first job of the batch. At the end of the job it would regain control and load and run the next until the batch was complete. Often the output of the batch would be written to magnetic tape and printed or punched offline. Examples of monitors were IBM's Fortran Monitor System, SOS (Share Operating System),and finally IBSYS for IBM's 709x systems in 1960.[2][3]
Third-generation systems[edit]
Third-generation computers[4] capable of multiprogramming began to appear in the 1960s. Instead of running one batch job at a time, these systems can have multiple batch programs running at the same time in order to keep the system as busy as possible. One or more programs might be awaiting input, one actively running on the CPU, and others generating output. Instead of offline input and output, programs called spoolers read jobs from cards, disk, or remote terminals and place them in a job queue to be run. In order to prevent deadlocks the job scheduler needs to know each job's resource requirements—memory, magnetic tapes, mountable disks, etc., so various scripting languages were developed to supply this information in a structured way. Probably the most well-known is IBM's Job Control Language (JCL). Job schedulers select jobs to run according to a variety of criteria, including priority, memory size, etc. Remote batch is a procedure for submitting batch jobs from remote terminals, often equipped with a punch card reader and a line printer.[5] Sometimes asymmetric multiprocessing is used to spool batch input and output for one or more large computers using an attached smaller and less-expensive system, as in the IBM System/360 Attached Support Processor.
Later history[edit]

From the late 1960s onwards, interactive computing such as via text-based computer terminal interfaces (as in Unix shells or read-eval-print loops), and later graphical user interfaces became common. Non-interactive computation, both one-off jobs such as compilation, and processing of multiple items in batches, became retrospectively referred to as batch processing, and the term batch job (in early use often 'batch of jobs') became common. Early use is particularly found at the University of Michigan, around the Michigan Terminal System (MTS).[6]
Although timesharing did exist, its use was not robust enough for corporate data processing; none of this was related to the earlier unit record equipment, which was human-operated.
Ongoing[edit]
Non-interactive computation remains pervasive in computing, both for general data processing and for system 'housekeeping' tasks (using system software). A high-level program (executing multiple programs, with some additional 'glue' logic) is today most often called a script, and written in scripting languages, particularly shell scripts for system tasks; in IBM PC DOS and MS-DOS this is instead known as a batch file. That includes UNIX-based computers, Microsoft Windows, macOS (whose foundation is the BSD Unix kernel), and even smartphones. A running script, particularly one executed from an interactive login session, is often known as a job, but that term is used very ambiguously.
'There is no direct counterpart to z/OS® batch processing in PC or UNIX® systems. Batch jobs are typically executed at a scheduled time or on an as-needed basis. Perhaps the closest comparison is with processes run by an AT® or CRON command in UNIX, although the differences are significant.'[1]
Modern systems[edit]
Batch applications are still critical in most organizations in large part because many common business processes are amenable to batch processing. While online systems can also function when manual intervention is not desired, they are not typically optimized to perform high-volume, repetitive tasks. Therefore, even new systems usually contain one or more batch applications for updating information at the end of the day, generating reports, printing documents, and other non-interactive tasks that must complete reliably within certain business deadlines.
Some applications are amenable to flow processing, namely those that only need data from a single input at once (not totals, for instance): start the next step for each input as it completes the previous step. In this case flow processing lowers latency for individual inputs, allowing them to be completed without waiting for the entire batch to finish. However, many applications require data from all records, notably computations such as totals. In this case the entire batch must be completed before one has a usable result: partial results are not usable.
Modern batch applications make use of modern batch frameworks such as Jem The Bee, Spring Batch or implementations of JSR 352[7] written for Java, and other frameworks for other programming languages, to provide the fault tolerance and scalability required for high-volume processing. In order to ensure high-speed processing, batch applications are often integrated with grid computing solutions to partition a batch job over a large number of processors, although there are significant programming challenges in doing so. High volume batch processing places particularly heavy demands on system and application architectures as well. Architectures that feature strong input/output performance and vertical scalability, including modern mainframe computers, tend to provide better batch performance than alternatives.
Scripting languages became popular as they evolved along with batch processing.[8]
Batch window[edit]
A batch window is 'a period of less-intensive online activity',[9] when the computer system is able to run batch jobs without interference from, or with, interactive online systems.
A bank's end-of-day (EOD) jobs require the concept of cutover, where transaction and data are cut off for a particular day's batch activity ('deposits after 3 PM will be processed the next day').
As requirements for online systems uptime expanded to support globalization, the Internet, and other business needs, the batch window shrank[10][11] and increasing emphasis was placed on techniques that would require online data to be available for a maximum amount of time.
Batch size[edit]
The batch size refers to the number of work units to be processed within one batch operation. Some examples are:
Myriad 4 1 1 – Audio Batch Processors
- The number of lines from a file to load into a database before committing the transaction.
- The number of messages to dequeue from a queue.
- The number of requests to send within one payload.
Common batch processing usage[edit]
Myriad 4 1 1 – Audio Batch Processor Pdf
- Efficient bulk database updates and automated transaction processing, as contrasted to interactive online transaction processing (OLTP) applications. The extract, transform, load (ETL) step in populating data warehouses is inherently a batch process in most implementations.
- Performing bulk operations on digital images such as resizing, conversion, watermarking, or otherwise editing a group of image files.
- Converting computer files from one format to another. For example, a batch job may convert proprietary and legacy files to common standard formats for end-user queries and display.
Notable batch scheduling and execution environments[edit]
Translator 1 2 1 equals. The IBM mainframez/OSoperating system or platform has arguably the most highly refined and evolved set of batch processing facilities owing to its origins, long history, and continuing evolution. Today such systems commonly support hundreds or even thousands of concurrent online and batch tasks within a single operating system image. Technologies that aid concurrent batch and online processing include Job Control Language (JCL), scripting languages such as REXX, Job Entry Subsystem (JES2 and JES3), Workload Manager (WLM), Automatic Restart Manager (ARM), Resource Recovery Services (RRS), DB2 data sharing, Parallel Sysplex, unique performance optimizations such as HiperDispatch, I/O channel architecture, and several others.
The Unix programs
