Dialogue mixing is the most basic and essential audio mixing style for podcasting and audiobooks. It focuses on making the spoken words clear, consistent, and natural. To achieve this, you need to use tools like EQ, compression, noise reduction, and volume automation. EQ can help you cut out unwanted frequencies and boost the clarity and presence of the voice. Compression can help you level out the volume and dynamics of the voice. Noise reduction can help you eliminate background noise and hum. Volume automation can help you adjust the volume of each speaker or section manually.

Employ compression to manage dynamic range, maintaining a consistent volume level throughout the episode. Use automation to adjust levels for quieter and louder segments, keeping the listener engaged without straining to hear.
Sound design mixing is the audio mixing style that adds sound effects, music, and ambience to your podcast or audiobook. It can help you create a more immersive and engaging listening experience. To achieve this, you need to use tools like panning, reverb, delay, and volume automation. Panning can help you create a sense of space and direction for your sound sources. Reverb can help you create a sense of depth and realism for your sound sources. Delay can help you create a sense of movement and echo for your sound sources. Volume automation can help you balance the levels of your sound sources and create transitions and fades.

Ensure your mix still sounds as expected on a few different types of speakers. Your monitors are almost certainly not what your production will be listened to with. Try cheap computer speakers, a couple of different headphones, your ear buds, and your car.
Stereo mixing is the audio mixing style that uses two channels to create a wider and more spacious sound. It can help you enhance the stereo image and separation of your podcast or audiobook. To achieve this, you need to use tools like panning, stereo width, and phase alignment. Panning can help you position your sound sources in the left and right channels. Stereo width can help you adjust the amount of difference between the left and right channels. Phase alignment can help you avoid phase cancellation and improve the coherence of your sound sources.

Remember to test your mix in mono as well. Phase problems are often very obvious in mono where they are easily missed in stereo.
Mastering mixing is the final audio mixing style that polishes and optimizes your podcast or audiobook for distribution. It can help you improve the overall quality and loudness of your sound. To achieve this, you need to use tools like EQ, compression, limiting, and dithering. EQ can help you fine-tune the frequency balance and tonal character of your sound. Compression can help you smooth out the dynamics and enhance the punch of your sound. Limiting can help you increase the loudness and prevent clipping of your sound. Dithering can help you reduce the noise and distortion of your sound.

La masterización para un podcast o audiolibro es un momento clave para el producto final. Aunque es verdad que muchos elementos se trabajan en la mezcla, no debemos pasar del lado el poder de una buena masterización; no debe quedarse en nuestra mente como un proceso que solo sirve para dar volumen. Sustraer algunas frecuencias para enfocar mejor los diálogos, cortar algunos espacios donde se titubea o se balbucea, comprimir toda la pista para darle continuidad, etc. Tómate tu tiempo y disfruta también el momento de masterizar, no todo termina en la mezcla!

Whichever style of mixing you prefer, it's always easier to get a better sounding end product if you put some time into the preparation at the outset. Noise reduction tools are great, but if you can improve your source signal, that's even better. You don't have to spend loads of money on high-end gear either. Here are two tips I found helpful: 1. Position your microphone(s) as close to the person as possible; and 2. Use things like pillows and draped duvets to reduce sound reflections and reverberations from solid walls. If you get the room sounding good, and you position your mics for a strong signal, then noise will be vastly reduced and you'll find the audio is much easier to mix.
