Hello Moocsters! I am David Sabalete from Barcelona in Spain. This lesson is for week 4 of Introduction To Music Production at Coursera.org. I will be writing about the "Concepts behind dynamic processors". I apologize for my level of English, which is not my mother tongue. There are two task we can to apply to our sound in order to manipulate its dynamic range: Compression Expanssion Compression means to reduce the dynamic range and Expanssion means to increase it. However it is more common to apply only one of them. When we want to reduce the dynamic range, we can make the loud part of the sound quiter or make the quiet part louder. We will get a more consistent performance or more consistent recording when we apply these changes to the sound. When we want to increase the dynamic range, we can make the loud part louder or make the quiet part quiter. Both operation increase the difference between the loud part and the quiet part. If we have a sound with ...

Hello Moocsters! I am David Sabalete from Barcelona in Spain. This lesson is for week 3 of Introduction To Music Production at Coursera.org. I will be writing about the "Categories of Effects". I apologize for my level of English, which is not my mother tongue. When working with sound in a mixing board, we can employ different audio effects to change the signal flow in different ways. When working in a DAW, these type of modifications are called  digital signal processing  or DSP. These audio effects can be organized into three different categories. These are the three categories, which are related to three of the principles of sound: Dynamic Effect.  It is related to amplitude. It controls volume based on the material over time. Compressors, Limiters, Expanders or Gates are exemples of type of effect. Delay Effect.  It is related to the propagation principle of sound. It adds little delays to the signal which give us sense of space. Reverbs, Delays, P...

Hello again! My name is David Sabalete from Barcelona and I will explain what is the checklist to follow in order to get your DAW ready to work. This is part of an assesment in the course IMPMOOC by Coursera. First of all, we need to name the file of the project appropriately. Usually within a folder in your computer where are stored all of the projects. This is good in order to have all well organized. Secondly, we need to adjust the Digital Audio Preferences . Although that may be done in the driver interface, I will do in my DAW, Sonar. The recommended preferences are: a sample rate of 48000Hz and a bit depth of 24 bit for recording. These parameters are accesible under Options menu / "Audio..." and then in the Audio Options Window. Due to limitations in the driver of my laptop, Sonar force me to set a sample rate of 44100Hz and a bit depth of 16 bits. Next, we need to set the recording file type . The recommended type is broadcast wave, or an uncompr...

Hello! I am David Sabalete from Barcelona in Spain. This lesson is for week 1 of Introduction To Music Production at Coursera.org. I will be writing about the "Visualizing Sound". I apologize for my level of English, which is not my mother tongue. Introduction The sound is something you can't see, so it is useful to have some way to see how it changes and understand. Technically speaking, sound is a longitudinal wave. It is difficult to represent, however in a DAW we have three different displays (among others) to help us to figure it out. These visualizers are: Oscilloscope Spectrum analyzer Sonogram/Spectrogram The following describes each of the different displays. The oscilloscope In this display with axes, the sound wave is based on two variables: the amplitude (vertical) and time (horizontal). The range of time may vary. In the Oscilloscope appearing in the materials is about 50 milliseconds, so it is a tiny period of time, but it depends on ...
