🌟 The Foundation of Audio Content Creation: Capturing Sound with Mono and Stereo!
Hello! This is ‘PHconlab’.
In our last session, we explored how to connect microphones using Audacity.
Now, let’s delve into the most fundamental yet crucial element of audio content creation: audio file types, namely Mono and Stereo.
Understanding how recorded sound is captured and played back is essential for producing high-quality audio content.
Through this guide, master the characteristics and usage of Mono and Stereo to elevate your audio production skills to the next level!
🎶 Understanding Audio File Types: Mono and Stereo!
When creating an audiobook, the most basic audio file types you need to know are Mono and Stereo.
When you record, sound is captured in the form of visible waveforms, and these are categorized into Mono and Stereo based on the number of waveforms.
-
Mono:
Sound waveforms are recorded as one. When listening through earphones or speakers, the sound is heard from both the left and right with the exact same volume and timing. It feels as if a single sound is heard in both ears simultaneously. Most audiobooks narrated by one person are typically recorded as Mono files.
-
Stereo:
Sound waveforms are recorded as two. These two waveforms are responsible for the left and right sounds, respectively. The volume and timing of each sound can be adjusted differently, creating a three-dimensional effect in the sound. For example, in an audio waveform, the upper part represents the left sound, and the lower part represents the right sound.
If a voice says ‘Hello, I’m Tony.’ and the upper waveform of ‘Hello’ is smaller than the lower waveform, while the upper waveform of ‘I’m’ is larger than the lower waveform, then ‘Hello’ will be heard softly in the left ear and loudly in the right ear, while ‘I’m’ will be heard loudly in the left ear and softly in the right ear.
By delivering different sounds to the left and right, you experience spatiality, similar to hearing a piano sound from the left or a violin sound from the right in music. The feeling of characters moving left and right in an audio drama is also possible because it’s a Stereo file. You can create such three-dimensional sounds by recording left and right sounds separately with two microphones, or by using a Stereo microphone.
🔄 Character Differences Between Mono and Stereo: Choosing the Right Fit for Your Content!
Even if the audio file’s format is Stereo, there are cases where the left and right waveforms are exactly identical in size or shape.
Such files may appear Stereo on the surface but actually sound like Mono. That is, they have the characteristic of a Mono file where the sound is heard only from the center.
-
Selection Based on Purpose:
- For audiobooks where spatiality or dimensionality is important, such as audio dramas or novels with multiple characters conversing, recording in Stereo is much more effective.
- Conversely, for audiobooks narrated by a single person, Mono is sufficient.
-
Platform Compatibility:
Most audio content platforms only allow uploading Mono or Stereo files, so understanding these two is sufficient.
🎛️ Multichannel Audio Files: The Potential for Richer Sound!
In addition to Mono (1 channel) and Stereo (2 channels), there are also 3.1 channel, 5.1 channel, and 7.1 channel formats.
-
Features:
This means the audio file contains more sound waveforms (e.g., 4, 6, or 8). As the number increases, the sound comes through more speakers, allowing for a richer and more three-dimensional sound experience.
-
Note for Beginners:
However, for those starting audiobook production, a basic understanding of this is sufficient.
