Why Object Pascal is More Than Meets the Eye: Exploring the Power and Versatility of Delphi and FreePascal

Published on in Pascal by - Comments

1. About Object Pascal

If you aren't familiar with Object Pascal, you might not know that it's been around for decades - and it's still going strong. Object Pascal is a programming language evolved from Pascal that has been used to create a variety of software applications, including desktop and mobile apps, as well as games. Despite its capabilities, many developers and programmers tend to regard Object Pascal as an inferior language, and it is often the subject of jokes and ridicule.

2. Reasons why Object Pascal is seen as inferior

One of the main reasons that Object Pascal is seen as inferior is that it is not as widely used as other languages, such as C, C++, Rust and so on. This lack of popularity can make it difficult for developers to find resources and support when working with Object Pascal, which can be frustrating and time-consuming.

Another reason that Object Pascal is often criticized is that it is associated with older, legacy systems. Many developers view Object Pascal as a "dated" language that … (read more)

Approaches for timing in digital audio workstations (DAWs)

Published on in DAW by - Comments
Today I want to write something about my still not released Digital Audio Workstation (DAW), namely about the timing within such a Digital Audio Workstation (DAW). 

Two approaches for timing in digital audio workstations (DAWs), at least as I have implemented them myself, are "MIDI-Time-Interval-per-Sample" and "Sample-Interval-per-MIDI-Time". 

The first "MIDI-Time-Interval-per-Sample" approach uses a 32.32bit fixed-point (with 64.64bit precalculations of some constants) value to represent the interval of MIDI time units per sample. It tracks the accumulated MIDI time by adding this interval to an accumulator for each sample processed. When the accumulator reaches a certain threshold, a MIDI event is processed and the accumulator is updated. With this approach it is also possible to determine a fractitional portion of the MIDI time unit, which can then be used for even more precise automation interpolation, for example.

The second "Sample-Interval-per-MIDI-Time" approach uses also a 32.32bit fixed-point … (read more)
