SEAMUS不是一個人？！美國電聲音樂學會大解密
SEAMUS是誰？其實它是美國電聲音樂學會（Society for Electro-Acoustic Music in the United States）的縮寫。這集小皮介紹：1984年由作曲家Barry Schrader發起、在CalArts召開首次會議；每年的全國大會（2027年在路易斯安那州立大學，主題包含AI）；從1987年開始頒發的SEAMUS Award，得主包括John Chowning、Max Mathews、Laurie Spiegel、Suzanne Ciani與巴倫夫婦；以及給學生的ASCAP/SEAMUS委託創作比賽。另外，林哪位老師的8聲道沉浸式電聲音景作品《Lava's Roaring Dance》也曾在2025年普渡大學的SEAMUS全國大會演出。
SEAMUS Isn't a Person?! Meet the Society for Electro-Acoustic Music in the United States
Who is SEAMUS? It's actually the Society for Electro-Acoustic Music in the United States. In this episode, Little Pi covers its founding in 1984 by composer Barry Schrader at CalArts, its annual national conference (2027 at Louisiana State University, with AI among the themes), the SEAMUS Award given since 1987 to John Chowning, Max Mathews, Laurie Spiegel, Suzanne Ciani, Bebe and Louis Barron and more, and the ASCAP/SEAMUS student commission competition. Plus, Teacher Lin Na-Wei's eight-channel immersive electroacoustic soundscape Lava's Roaring Dance was performed at the 2025 SEAMUS national conference at Purdue University.
第一部全電子配樂電影！《禁忌星球》背後的巴倫夫婦Bebe & Louis Barron
1956年科幻電影《禁忌星球》（Forbidden Planet）的配樂沒有任何傳統樂團，全部是電子聲音，幕後功臣是巴倫夫婦（Bebe & Louis Barron）。這集小皮介紹他們：結婚禮物是一台磁帶錄音機，在紐約格林威治村開了可能是美國第一間電子音樂工作室，幫約翰·凱吉剪接《Williams Mix》；受維納《控制論》啟發，故意讓自製電路過載來產生聲音；片頭字幕因工會問題只能寫「Electronic Tonalities」。
The First All-Electronic Film Score: Bebe and Louis Barron and Forbidden Planet
The 1956 sci-fi film Forbidden Planet has a score with no traditional orchestra at all, only electronic sounds, created by the married couple Bebe and Louis Barron. In this episode, Little Pi tells their story: a tape recorder received as a wedding gift, a studio in Greenwich Village that may have been the first electronic music studio in the United States, engineering John Cage's Williams Mix, and building circuits inspired by Norbert Wiener's Cybernetics that they deliberately overloaded to make sound. Because of a union issue, the film credits could only say Electronic Tonalities.
為什麼混音要用監聽喇叭？監聽喇叭怎麼選、怎麼擺
家裡的音響讓音樂更好聽，監聽喇叭卻要讓你聽見聲音本來的樣子。這集小皮介紹監聽喇叭為什麼追求平直的頻率響應、主動式和被動式的差別、低音單體尺寸要跟著房間大小挑，以及比價錢更要緊的擺位：等邊三角形、高音單體對準耳朵、離後牆遠一點；最後聊聊以「不討好」出名的經典Yamaha NS-10，和混完音多換幾種設備聽的好習慣。
Why Mix on Studio Monitors? How to Choose and Place Them
Home stereos make music sound nicer, but studio monitors let you hear the sound as it really is. In this episode, Little Pi explains why monitors aim for a flat frequency response, the difference between active and passive monitors, why woofer size should match your room, and why placement matters more than price: an equilateral triangle, tweeters at ear height, and some distance from the back wall. Finally, meet the famously unflattering Yamaha NS-10 and learn the habit of checking your mix on several different devices.
不用碰就能演奏！特雷門琴女王克拉拉·羅克摩爾Clara Rockmore
有一種電子樂器手完全不用碰就能演奏，它就是特雷門琴。這集小皮介紹特雷門琴女王克拉拉·羅克摩爾（Clara Rockmore）：四歲考進聖彼得堡音樂院的小提琴神童，青少年時因手臂肌腱發炎放下琴弓，在美國結識發明家萊昂·特雷門後成為特雷門琴最知名的演奏家，發展出獨特的空中指法；1977年專輯《The Art of the Theremin》由羅伯特·穆格夫婦製作、姊姊娜迪亞·萊森伯格鋼琴伴奏。
Playing Without Touching: Clara Rockmore, Queen of the Theremin
There's an electronic instrument you can play without touching it at all: the theremin. In this episode, Little Pi introduces Clara Rockmore, queen of the theremin. A violin prodigy admitted to the Saint Petersburg Conservatory at age four, she gave up the violin after developing tendinitis as a teenager. After meeting inventor Leon Theremin in America, she became the instrument's best known player and developed her own aerial fingering technique. Her 1977 album The Art of the Theremin was produced by Robert and Shirleigh Moog, with her sister Nadia Reisenberg on piano.
為什麼每首歌上串流平台都一樣大聲？響度LUFS是什麼
為什麼在串流平台上一首接一首聽，音量卻都差不多？這集小皮從「響度戰爭」講起，介紹依照ITU-R BS.1770標準、模擬人耳聽感的響度單位LUFS：數字通常是負的、越接近0越大聲，歐洲廣播標準EBU R128建議負23 LUFS，Spotify預設播放在負14 LUFS左右；再聊平台的響度正規化，為什麼硬壓得很大聲的歌反而吃虧，以及自己做音樂時該怎麼留峰值空間。
Why Do All Songs Sound Equally Loud on Streaming? What Is LUFS?
Why do songs on streaming platforms all sound about equally loud, one after another? Little Pi starts with the loudness war, then introduces LUFS, the loudness unit defined by the ITU-R BS.1770 standard that imitates how human ears hear. LUFS numbers are usually negative, and closer to zero means louder: the EBU R128 broadcast recommendation targets minus 23 LUFS, while Spotify plays back at around minus 14 LUFS by default. Finally, learn how loudness normalization works, why over-squashed masters lose out, and why you should leave headroom for peaks in your own music.
轉旋鈕、踩踏板，電腦怎麼知道？MIDI CC控制訊號是什麼
MIDI鍵盤上的旋鈕、推桿、踏板一動，電腦裡的聲音就跟著變，背後的功臣就是MIDI CC（控制變更）。這集小皮帶你看懂一則CC訊息的組成——控制編號加上數值，範圍都是0到127；認識最常見的幾個編號：1號調變輪、7號音量、10號左右位置、11號表情、64號延音踏板；最後聊聊在編曲軟體裡畫CC曲線做自動化的用法。
Twist a Knob, Press a Pedal: What Is MIDI CC?
Turn a knob, push a fader, or press a pedal on a MIDI keyboard, and the sound in your computer changes. The hero behind it is MIDI CC (Control Change). In this episode, Little Pi explains what's inside a CC message: a controller number plus a value, both ranging from 0 to 127. Meet the most common numbers: 1 for the modulation wheel, 7 for volume, 10 for pan, 11 for expression, and 64 for the sustain pedal. Finally, learn how drawing CC curves in your music software creates automation.
同一首歌換藍牙耳機音質差這麼多？SBC/AAC/aptX/LDAC是什麼
同一首歌換一副藍牙耳機聽起來差這麼多，關鍵其實藏在音訊編碼裡。這集小皮帶你搞懂SBC、AAC、aptX、LDAC這幾個常見編碼的差異：SBC是藍牙規範裡人人都要支援的基本款，AAC是蘋果生態系愛用的編碼，aptX主打低延遲、LDAC主打高解析度，最後也整理挑選重點，教你怎麼從iPhone或Android裝置判斷該注意哪個編碼。
Same Song, Different Sound: What Are SBC/AAC/aptX/LDAC Bluetooth Codecs?
The same song can sound noticeably different depending on which Bluetooth headphones you use, and the reason is hiding in the audio codec. In this episode, Little Pi breaks down SBC, AAC, aptX, and LDAC: SBC is the baseline every Bluetooth device must support, AAC is the codec favored by the Apple ecosystem, aptX focuses on low latency, LDAC focuses on high resolution, and finally, how to tell which codec to look for depending on whether you use an iPhone or an Android device.
被送上太空的電腦作曲家蘿莉·史匹格 Laurie Spiegel
1977年旅行者號太空船帶著一張金唱片飛出太陽系，開場的其中一首曲子，是電腦作曲家蘿莉·史匹格的作品。這集小皮介紹她：從自學民謠吉他，到在貝爾實驗室用早期電腦系統創作、參與開發電腦繪圖系統，1980年專輯《The Expanding Universe》被公認是環境音樂的重要作品，1986年推出讓一般人也能玩演算法作曲的軟體《Music Mouse》。
Her Music Flew Into Space: Computer Composer Laurie Spiegel
In 1977 the Voyager spacecraft carried a golden record out of the solar system, and one of the pieces opening its \"Sounds of Earth\" section was by computer composer Laurie Spiegel. In this episode, Little Pi introduces her: from self-taught folk guitar to making music on early computer systems at Bell Labs and helping develop computer graphics systems, her 1980 album \"The Expanding Universe\" hailed as a landmark of ambient music, and \"Music Mouse\" (1986), software that let anyone play with algorithmic composition.

How to Choose a Microphone: Dynamic, Condenser, and Polar Patterns
Want to start recording or make a podcast, but dynamic, condenser, and polar patterns have your head spinning? In this episode, Little Pi explains it simply: why dynamic microphones are tough and great for live use, why condenser microphones are sensitive but need 48-volt phantom power, how to read cardioid, omnidirectional, and figure-eight patterns, and the difference between USB and XLR connections, then how to choose based on your situation.
用電腦寫出第一段音樂！電腦音樂之父馬克斯·馬修斯 Max Mathews
這集小皮介紹被尊稱為「電腦音樂之父」的馬克斯·馬修斯（Max Mathews）。他原本是貝爾實驗室的電機工程師，1957年在IBM 704大型電腦上寫出第一個電腦音樂程式MUSIC，1961年團隊讓電腦合成人聲演唱《黛西貝爾》，這段示範後來還成為《2001太空漫遊》中哈爾九千唱歌橋段的靈感來源。他提出的「單元產生器」積木式設計概念，影響了Csound、SuperCollider、ChucK等後來所有的音樂程式語言。
Writing Music with a Computer for the First Time! Max Mathews, Father of Computer Music
In this episode, Little Pi introduces Max Mathews, honored as the "father of computer music." An electrical engineer at Bell Labs, he wrote MUSIC, the first computer music program, on an IBM 704 mainframe in 1957. In 1961 his colleagues had a computer sing "Daisy Bell" with a synthesized voice, a demo that later inspired the scene where HAL 9000 sings in "2001: A Space Odyssey." His "unit generator" building-block design shaped Csound, SuperCollider, ChucK, and nearly every music programming language since.
可口可樂那聲「啵」是她做的？被葛萊美提名五次的合成器先驅蘇珊妮·奇亞尼

Who Designed That Coca-Cola "Pop"? Synthesizer Pioneer Suzanne Ciani
That iconic pop-and-fizz sound in Coca-Cola commercials was actually designed by a composer using a synthesizer. In this episode, Little Pi introduces a legend of electronic music - Suzanne Ciani. A top expert on the Buchla modular synthesizer, she built her name through commercial sound design, pioneered the New Age music genre with her album "Seven Waves," earned five Grammy nominations, and was rediscovered by a new generation after years out of the spotlight, returning to the stage for live modular synthesizer performances.
耳機百百款到底怎麼選？監聽耳機、降噪耳機一次搞懂
入耳式、耳罩式、開放式、封閉式……耳機種類多到讓人頭昏眼花？這集小皮用最簡單的方式，一次搞懂耳機的四大分類、監聽耳機跟一般消費耳機的差別，還有主動降噪（ANC）背後的原理，最後依通勤、混音創作、運動健身三種使用情境，教你怎麼挑一副真正適合自己的耳機。
How to Choose Headphones: Studio Monitors, Noise Cancelling, and More
Earbuds, over-ear, open-back, closed-back... headphone types can be overwhelming. In this episode, Little Pi breaks down the four main headphone categories, explains the difference between studio monitor headphones and regular consumer headphones, and shows how active noise cancelling (ANC) actually works. Then, based on three real-life scenarios - commuting, mixing and music production, and working out - Little Pi helps you find the headphones that are actually right for you.
合成器怎麼「捏」出聲音？減法合成與ADSR包絡
接續上一集的MIDI，這集小皮講合成器怎麼真正「發出聲音」——先用振盪器做出一個泛音超豐富、又吵又刺耳的原始波形，再用濾波器把不要的頻率削掉，最後靠ADSR包絡線（起音、衰減、延持、釋音）決定聲音的個性。同一個波形調一調包絡，就能從打擊聲變成拉弦樂器那種鋪底音色，這套邏輯幾乎所有合成器都通用。
How Does a Synth Actually "Sculpt" Sound? Subtractive Synthesis and the ADSR Envelope
Following up on MIDI, Little Pi explains how a synthesizer actually makes a sound: an oscillator generates a raw, overtone-rich, harsh waveform, a filter carves away the unwanted frequencies, and the ADSR envelope (attack, decay, sustain, release) gives the sound its personality. Tweak the envelope on the exact same waveform and you can go from a drum hit to a lush string-like pad - a logic that applies to nearly every synthesizer out there.
MIDI到底是什麼？不是錄音檔，是一張演奏指令表
MIDI檔案裡其實完全沒有錄到聲音？這集小皮解釋MIDI跟MP3、WAV的根本差別——它記錄的不是聲波，而是一張精細的演奏指令表。從1983年讓不同品牌合成器互相溝通的標準誕生，講到為什麼MIDI檔案這麼小、還能隨時換樂器演奏，以及它四十幾年來一直被遊戲配樂、電影配樂、AI作曲工具使用的原因。
What Is MIDI, Really? Not a Recording, an Instruction Sheet
A MIDI file doesn't actually contain any recorded sound? Little Pi explains the core difference between MIDI and MP3 or WAV: it doesn't store a waveform, it stores a detailed performance instruction sheet. From the 1983 standard that let synthesizers from different brands talk to each other, to why MIDI files are so tiny and can switch instruments instantly, to why it's still used everywhere from game scores to AI music tools over forty years later.
MP3、AAC、FLAC、WAV到底差在哪？音樂檔案格式一次搞懂
同一首歌，MP3只要幾MB，WAV卻要幾十MB？這集小皮解釋有損／無損壓縮的差別，帶大家搞懂MP3、AAC、FLAC、WAV這幾個常見音樂檔案格式到底差在哪，還有平常聽歌、重視音質、進錄音室後製，各自該怎麼選。
MP3 vs AAC vs FLAC vs WAV: What's the Real Difference?
Same song, wildly different file sizes: MP3 is a few MB, WAV is dozens of MB. Little Pi explains lossy vs lossless compression and breaks down MP3, AAC, FLAC, and WAV, plus which one to pick for casual listening, quality-focused listening, or studio production.
顫音轉太快，意外發明整個80年代的聲音！FM合成之父約翰·喬寧
史丹佛教授John Chowning在1967年做顫音實驗，把「搖晃速度」開到遠超正常範圍，意外發現FM合成技術，後來授權給Yamaha做出DX7合成器，定義了整個80年代流行樂音色，2026年2月終於拿到葛萊美技術獎。
He Cranked a Vibrato Too Far and Invented the Sound of the 80s: John Chowning and FM Synthesis
Stanford professor John Chowning was experimenting with vibrato in 1967 and pushed the wobble speed far past any normal range, accidentally discovering FM synthesis. Yamaha later licensed the technology to build the DX7, which defined the sound of 1980s pop music. In February 2026, Chowning finally received a Technical Grammy Award for the discovery.
取樣率是什麼？CD音質背後那個怪數字44.1kHz是怎麼來的
「電聲小知識」系列首發！CD音質常寫著44100這個怪數字，這集小皮解釋取樣率是什麼、奈奎斯特取樣定理，還有44100這個零頭其實是1980年代CD規格制定時，向錄影帶技術妥協留下的歷史遺跡。
What Is Sample Rate? The Strange Number Behind CD Audio Quality
First episode of a new mini-series on everyday audio-tech trivia. CD audio quality is always labeled 44100, an oddly specific number. Little Pi explains what sample rate actually means, the Nyquist sampling theorem, and how that leftover 100 traces back to a compromise with 1980s videotape technology.
用畫的畫出一首歌？！Oramics發明人戴芬·奧蘭姆
有人在還沒有電腦繪圖軟體的年代，就想到「乾脆用畫的畫出聲音」！介紹英國電子音樂先驅戴芬·奧蘭姆——她共同創辦了BBC的Radiophonic Workshop電子音效部門，卻在成立不到一年後就自己辭職，全心投入研發Oramics：一台能把手繪波形轉換成聲音的機器，概念上早就預告了今天音樂軟體裡的自動化曲線。
She Drew Sound Onto Film: Oramics Inventor Daphne Oram
Someone figured out how to draw sound long before graphic design software even existed.
