Question

我在流动世界中看到一个方案家。我愿在我的音乐博览会的支持下提出申请。我怀疑一个有音乐家的移动电话,可以很容易地安排节目,支持典型的音乐家实践课程。

Should be Easy: Play an A at 440 Hz (or 438,442) for tuning.
Should be easy: Metronome with beat patterns
The fun part: I hit a simple record, play a snippet, and can play it back so I can hear the notes I missed. You can almost do this with some sound recorders - but the need to clumsily select a file, save, open a different app to play back, usually makes it unusable. The value add is found in making this extremely easy.

技术方面:

A microphone and existing API for sound input. The ability to use an external microphone would be even better.
Access to media player APIs without the need to open external apps or do clunky things with files.
Adequate access to playback API to create specific notes and beat patterns.
As a hobby application, this should not require expensive tooling. I can switch to a new phone to use the application.
Bonus points for something that easily ports to a netbook.

我将向世界提供性电话。目前,我使用陈旧的语音装置,使用文字信息。我得 won地揭示了我目前的方案拟定工作,因为学习一个新平台是很出色的。

Answer 1

我必须走下去,建议安乐,或许是黑莓。

理由:

iPhone apps are written completely in Objective-C and C. Porting it requires additional effort and you seem to desire something that sits on a netbook.
iPhones tend to be expensive (although you can get a cheapo iPod touch no problem)

然而,Piper为第1、2和3点提供了大量支持。因此,如果能满足你们的要求,那么发展的方便程度很可能会落到“i”上。便携式和开发案例来自安伯和黑莓。

Answer 2

计算机目前缺乏一种良好的方法,无法产生与实际手段一样健全的说明。为此,你将必须建立整个自动备用金信封。或者使用预先记录的音响,并使用不同的幻灯和时间。

早餐会、录音和击.很容易。

不知道任何其他电话。我确实享有奥比奇。

Answer 3

我建议Pi。核心视听图书馆很广,使你能够利用视听工具箱功能进行取样,或实时产生低距离的音频。

在栅栏的另一边,安德列斯视听图书馆需要更多的密码,以进行简单的取样。甚至连线对准声和生成和(或)处理实时音频所需的性能也并不接近。
