Чтение книги онлайн.

СКАЧАТЬ studio work.

      Volume 1 presents a preface, specifying the contents and the writing conventions used, then an introduction followed by four chapters, a conclusion and five appendices:

       – recording history;

       – voice;

       – microphones;

       – acoustic environment.

      The conclusion summarizes the main topics discussed and introduces the concepts that will be addressed in the second volume.

      Appendices 1–5 provide some additional information. You will find in this order:

       – sound unit;

       – audio connectivity;

       – audio processing plugins;

       – tube and JFET mic amplifiers;

       – microphone pairs.

      Volume 2 presents a preface and an introduction identical to those of Volume 1 followed by four chapters, a conclusion and five appendices:

       – processing hardware and software;

       – configuration and audio channel;

       – voice recording;

       – special effects.

      Appendices 1–4 are taken from Volume 1 to complement the previous chapters by including:

       – sound unit;

       – audio connectivity;

       – audio processing plugins;

       – microphone pairs.

      Appendix 5 of Volume 2 provides details on the types of software plugins available from different vendors and operating systems.

      The conclusion sheds light on the whole book and gives a brief overview of the future evolution of voice recording.

      Each volume can be read separately. While there are concepts that are dependent on another chapter, references to the relevant sections are given. However, the first two chapters of Volume 1, devoted to the history of recording and to the human voice, provide a contextual basis for the understanding of several notions that you will find in the following chapters.

      If you’re a novice on the subject, I strongly advise you to read them first, to discover the basics of the subject of this book.

      For the others, I hope that you will discover new notions that will enrich your knowledge.

      At the end of each volume, you will find a reference list and a list of Internet links.

      A glossary is also present; it will explain some acronyms and terminologies very specific to sound recording, recording and mixing.

      Conventions

      This book uses the following typographical conventions:

      Italics, which are reserved for important terms used for the first time in the text which may be present in the glossary at the end of the book, mathematical terms, comments, equations, expressions or variables.

      Remarks are indicated by the presence of the keyword: NOTE. They complete the explanations already provided.

      The figures and tables all have a legend that is often useful for understanding.

      Vocabulary and definition

      As with all techniques, voice recording has its own vocabulary. Certain words, acronyms, abbreviations, initialisms and proper names are not always familiar and will be included in the glossary.

      Acknowledgments

      I would especially like to thank the ISTE Ltd team and my editor Chantal Ménascé, who trusted me.

      Finally, I would like to thank my wife, Vanna, and my daughters Océane and Léa who supported me throughout the writing of this book.

      Introduction

      Since Plato and Aristotle, we have often heard this quote, “The voice is the mirror of the soul”. It is true that before understanding the meaning of a word, we must understand its emotional side; we recognize the intonation that makes a voice more or less unique. The paralinguistic characteristics of a voice, that personalize it, take priority over the meaning of the message that is delivered. They express the emotional aspect of the interlocutor and favor the transmission of emotions.

      It is also necessary to take the environment into consideration; the voice exists only through its medium, the air which surrounds us. The numerous acoustic variables, vocal cords and different morpho-anatomical cavities of the individual form the timbre of the voice, which can be modified during its diffusion by the environmental medium in which it is established.

      Each individual has a different timbre that represents a sound signature. The voice is the reflection of the body and the spirit, but let us not assume that its characteristics are as static and reliable as the genetic code or fingerprints. They are variable, determined by numerous parameters linked to morphology, imagination, environment, affect and even gestures, even if many of these elements do not affect the hard core that builds the essence of a voice.

      The recorded voice brings different sensations that often flout the canons of the direct voice, spoken or sung, but it is far from being unpleasant and it has become, by force of things, a standard. Our world is constantly saturated with music or recorded voices; few people can claim to have heard a particular performer with his or her live voice. Voices are optimized for recording and broadcasting; they must remain intelligible and are sometimes enriched, or even placed in a virtual environment, but our ears have become accustomed.
