Sound Synthesis and Sampling聲音合成和取樣

Basics of a Music Sampler and a Synthesizer Explained.基本的音樂採樣器和合成器的解釋。
It is possible to digitise real world sounds with an ADC (analogue to digital converter).這是有可能的數字化現實世界的聲音與它們的一個ADC (模擬數字轉換器) 。 A sample is then taken of the amplitude of the analogue wave form. (Tascam and Motu use adc and dac, if you are a hip hop or jazz producer this article teaches and helps you learn the basics) 樣本 ,然後採取振幅的模擬波形。 ( Tascam和令使用ADC和DAC ,如果你是一個嘻哈爵士樂生產者或本條任教,並幫助你學習的基礎)
Frequencies are made by play back of the ‘sequential sample amplitudes’ at a specified rate. 頻率是由播放的'序貫抽樣振幅'在指定率。 The recording is determined by the sample rate which determines the frequency response. 記錄是由採樣率決定了頻率響應。
The sampling rate can only reproduce frequencies that are half of the sample rate (Nyquist).該採樣率只能再現頻率是一半的採樣率(奈奎斯特) 。 Foldover could occur when sampling records frequency above the Nyquist frequency.折疊時可能發生的頻率採樣記錄以上的奈奎斯特頻率。 These frequencies may be shown at lower frequencies when recorded.這些頻率可顯示在較低頻率時,記錄在案。
ADC will normally use filters to prevent such frequencies from being recorded and when these waveforms are being produced synthesizers users will normally want band limiters of samples so that fold back is not an issue.模數轉換器將通常使用的過濾器來防止這種頻率記錄和波形時,這些正在生產合成器的用戶通常會想帶限制器的樣品,以便倍回來不是一個問題。
The sample is then quantized to give it a value that represents the amount of bits available for each sample (The number zeros and ones).樣本,然後量化給它一個價值,代表的數額位可用於不同樣本(人數零的) 。 When a sample is quantized, the amplitude of the sound wave is rounded to the nearest available digital value (approximation).當一個樣本量化,振幅的聲波是四捨五入至最接近的現有數字值(近似) 。 Less bits more approximation.減位更加逼近。 There is an approximation error which is the difference between the analogue value and digital value.有一個近似誤差的區別是模擬和數字價值的價值。
Large approximation error equals large quantizing noise being produced.大逼近誤差等於量化噪聲大生產。 Larger sample sizes or bit depth reduces the amount of noise, corresponding to the dynamic range of the system.較大的樣本大小或位元深度減少了噪音,相應的動態範圍的系統。
Hip hop producers will not need to understand this level of detail but sound designers and vst plugin writers will.嘻哈生產者將沒有必要理解這一點的詳細程度,但健全的設計師和作家的VST插件會。

Modern Samplers and Synthesizers have over-lapping functionality, which leads to confusion by beginner jazz and hip hop producers.現代採樣和合成有超過研磨功能,從而導致混亂的初學者爵士樂和嘻哈生產者。 Samplers don’t have synthesis generation capabilities of oscillation for wave creation or other modelling types.採樣沒有合成能力的一代波振盪創造或其他模擬類型。 A pre-recorded digital audio file sample is used as sound source synthesis type filtering, gating or modulation is utilized for sophisticated effects processing with digital audio file editing that changes the sound of the sample.阿預先錄製的數字音頻文件樣本作為聲源的綜合型過濾,門或調製是利用先進的效果處理的數字音頻文件編輯改變的聲音樣本。

A Sampler is either stand-alone hardware, which is normally part of a musical instrument/dj equipment or software.阿採樣或者獨立的硬件,這通常是部分樂器/山設備或軟件。 The sampler gives the opportunity to record a sound formed in a number of ways in a digital format.該採樣器提供了機會,一個健全的紀錄中形成了一些方式的數字格式。 Using principles similar to those mentioned at the start of this document.用類似的原則提到的那些開始時,此文件。 The sample file can be a musical recording, natural occurrence, or even electronic sounds produced by a synthesizer. Samplers increase the quantity of instrument sounds and effects that music makers can work with.示例文件可以是音樂錄音,自然發生,甚至電子音樂製作合成器。採樣的數量增加了樂器的聲音和影響,音樂製造商可以工作。 Samplers are purchased with pre-recorded samples, and some samplers can also be interfaced with MIDI keyboard/controller with the digital out routed to a hardware/software mix or analogue out to audible speakers.採樣器是購買預先錄製的樣本,以及一些採樣器還可以連接的MIDI鍵盤/控制器,數字出送到一個硬件/軟件混合或模擬聲響了發言。 The sample can then be utilized in a sequencing project (MIDI and digital audio tracks combined) or imported into a waveform editor for further editing.樣本就可以利用在測序 項目 ( MIDI和數字音頻軌道合併)或進口到波形編輯器作進一步修改。 Modern sampler models are often capable of up to 128-note polyphony.現代採樣模式往往能夠達到128複音的說明。 Eg if a Piano sample is loaded on the sampler then several octaves of piano samples are loaded.例如,如果一個鋼琴樣品裝上採樣然後幾個八度的鋼琴樣品的加載。 Trigger of notes can be then be achieved with a MIDI keyboard if MIDI compatible). 觸發的音符然後可以實現的,如果MIDI鍵盤的MIDI兼容) 。 Some samplers come with an integrated sequencer that allows the creation of patterns with the samples.有些採樣器帶有一個綜合的音序器,從而創建模式的樣本。 The Sampler outputs in digital data stream can is normally routed into a Mixer or directly to a computer with a multi-track audio application and can be recorded as a track in a project.採樣器輸出的數字數據流通常是可以路由到調音台,或直接向計算機多軌音頻應用 ,可以被記錄為一個軌道的一個項目。
