- 相对于 Matlab，Octave如何? - 知乎
octave唯一的优点也就是占内存小了（< 500M），然而不知是不是安装的姿势不对，每次打开软件 跑个小命令，简直比PS和AE还慢。
- What is an octave? - Music: Practice Theory Stack Exchange
An octave is simply an interval created by the use of the factor 2 instead - e g if we started with our 100Hz note again, and we wanted to go up an octave, we would double the frequency, taking us to 200Hz If we wanted to go down an octave, we'd halve it, taking us to 50Hz Why is this factor of 2 so special?
- 有了python, R，使用Octave做机器学习必要性在哪里？ - 知乎
用Octave作为入门的优点有以下： [1] Octave与Matlab兼容非常好，学会用Octave，再去用Matlab 简直无缝连接，很多大公司或者科研单位都是用Matlab作为主要数据处理和开发工具，包括我待过的美国国家实验室和中科院某所大科学装置实验室，Matlab都是主要使用工具
- Scilab,Octave,Sagemath区别与比较? - 知乎
该页面讨论了Scilab、Octave和Sagemath的区别与比较，适合非数学专业的人士自学数学时参考。
- Why are there twelve notes in an octave? - Music: Practice Theory . . .
It makes me wonder if the 12-semitone octave sounded good before the advent of "music as we know it" or if it is something of an acquired taste, in which case alternative breakdowns of the octave could be adapted to, like in the case of western vs indian vs east asian music
- tuning - Was the term octave coined after the development of early . . .
Was the term “octave” coined after the development of early music theory? No As shown below, it was already in use by the 11th century to denote the musical interval (although the principal name for the interval at that time seems still to have been diapason) What system was in use in medieval Europe when the term octave arose, and what did the term octave refer to? I'm a little hazy on
- Is 16va proper notation? - Music: Practice Theory Stack Exchange
The basis of both the frequency and the cents measurement is a 2:1 octave relationship Because pitch measurement systems (linear and logarithmic) are derived from the octave as 2:1, a double octave represented as 16va (16:8 = 2:1) is a notation evolution surpassing music theory symbols based on an outdated, extended modal scale series, like 15ma
- Why do octaves sound equivalent? - Music: Practice Theory Stack Exchange
@CarlWitthoft: Octave equivalence isn't the statement that notes separated by an octave sound the same If I play 1000 Hz followed immediately by 2000 Hz, all humans can tell that there was a big change in pitch Octave equivalence says that these two pitches are perceptually similar in a variety of ways Depending on context, they can be easily confused with one another Across all musical
