Hello my friend! Recently, Gumroad removed the feature of receiving payments through PayPal, and currently only allows Stripe or bank accounts for receiving payments. As a Chinese individual, neither of these options are viable, so I am unable to receive the money earned from sales into my personal account. Gumroad doesn't seem to prioritize this issue, hence I have decided to switch to selling my work on Kofi. Please visit https://ko-fi.com/darlinglee/shop to purchase my work or subscribe. I will resume using Gumroad for sales once they provide viable payment methods for us Chinese users. Thank you for your support.

您好我的朋友！前段时间Gumroad撤销了使用paypal左右收款账户的功能，目前只能使用Stripe或者银行账户作为收款方式，作为中国人，这两种方式都无法使用，因此销售所得的金钱都不能收款到我的个人财产中。Gumroad似乎对这个问题并不重视，因此我已经尝试转到Kofi中销售我的作品。请前往 https://ko-fi.com/darlinglee/shop 购买我的作品或进行订阅。待Gumroad重新为我们中国人提供可用的收款方式后再重新使用Gumroad进行销售，谢谢您的支持。

This is an advanced sound phase positioning tool that allows you to adjust the left-right and front-back position of the sound.

For adjusting the front-back position, a relatively simple directional effect is achieved by boosting or attenuating a specific frequency band.

As for adjusting the left-right position, three modes are provided: separate mode, alternating mode, and virtual reality sound mode：

1.Separate mode: The left and right channels are separated and attenuated independently, similar to the way in Protools. For example, when adjusted to the extreme right, the right channel outputs the original right signal 100%, while the left channel outputs the original left signal 0% (mute).

2.Alternating mode: Similar to the separate mode, but when the left and right channels are separated and attenuated, the signal of the attenuated side is compensated to the other side. For example, when adjusted to the extreme right, the right channel outputs the original right signal 100%, while the left channel outputs the original left signal 0% (mute), and the 100% attenuated signal from the left side is output to the right side. This method ensures that all channel signals are retained when adjusting the sound phase of the stereo audio, such as when adjusted to the extreme left, the output from the left channel is a mono audio of the merged left and right channels without losing the original right signal.

3.Virtual Reality Audio mode: The left-right direction of sound is perceived by the brain through analyzing the time difference of the signals received by the two ears. This method calculates the maximum delay range on both sides by combining the distance between the two ears (taking a reasonable length value) and the speed of sound propagation in the air, and delays one channel to achieve a perceived sound phase shift. This method does not attenuate the energy of the left and right channels, and the values on the level meter will not change. Therefore, this method cannot achieve the effect of extreme left or right, and is more obvious in mono (or center-channel) audio.

V2.0 Update Log:

1. The control method of left and right, front and back has been removed, replaced by angle and depth. Now you can control the orientation of the entire sound using a single knob;
2. Changes in plugin UI and operation methods;
3. The Chinese and English versions are merged into one. You can manually switch the language of the plugin interface;
4. Optimized the logic of implementing sound front and back orientation.
   

这是一个高级声相摆位工具，您可以用它调节声音的左右和前后位置。

关于前后位置的调节方法，是一个相对简单的特定频段增减带来的方位效果；

而对于左右位置的调节，我提供了三种模式：分离模式，交替模式和虚拟现实声音的模式：

1.分离模式：左右声道分离进行衰减。类似于Protools的方式。比如调到极右，则右边输出原本右边信号100%，左边输出原本左边信号0%（静音）。

2.交替模式：类似与分离模式，但不同的是，左右声道分离进行衰减的时候，被衰减一方的信号会被补偿给另外一方。比如调到极右，则输出原本右边信号100%，左边输出原本左边信号0%（静音），同时左边被衰减的100%信号给到右边输出。此种方式能保证立体声音频调整声相的时候可以保留所有的声道信号，比如调到极左时，左边输出的是左右声道合并成一个完整信号的单声道音频，而不缺失原本右边的信号。

3.虚拟现实音频模式：人耳分辨声音的左右方位是通过大脑分析两只耳朵接收到信号的时间差来感知的，此种方法就是通过两只耳朵之间的距离（取一个合理的长度值），结合声音在空气中传播速度等常量来计算两边的最大延迟范围，用于延迟一个声道的方法达到听感上的声相偏移。这种方法不会对左右声道的能量进行衰减，电平表上的数值不会改变。因此方法无法得到极左极右的效果，而且在单声道（或中置音频）更明显。

V2.0更新日志：

1.取消了左右，前后的控制方式，取而代之的是角度和深度，现在您可以使用一个变量控制整个声音的方位了；

2.插件UI和操作方式变更；

3.中英文版本合二为一，您可以手动切换插件界面语言了；

4.优化声音前后方位实现的逻辑
