ViPER4Android音效 XHIFX版 - 2.3.3

PS：此为飞哥作品，为了扩大规模效应，我特代以发布
【注意】
手机必须要ROOT，且必须安装过Busybox。如果您不懂什么是ROOT、什么是Busybox，请不要安装该应用！
【运行环境：仅用于 Android 2.3.3 - 2.3.x 版本，因此根据你的系统版本仔细选择！】
此为系统级别高级应用，如果您不知道它用来做什么的，请仔细阅读说明。
针对此神作，请给予五星支持！
系统设置-----关于信息---可以查看到您手机系统的安卓版本号

【程序说明】
1、ViPER 4 Android简称V4A。
2、ViPER 4 Android FX 和 XHiFi 版本我应该选择哪个？
FX版本内包含有很多效果器，而XHiFi版本只有还原/增强细节的选项。如果你喜欢各种效果(比如环绕、低音、混响等等)那就安装FX版本，如果你喜欢听直白的人声且拥有一个不错的耳机那就安装XHiFi版。

【请注意】
在无浮点运算能力的平台上（NOVFP），脉冲反馈和耳机环绕引擎+效果是无效的。

【BUG】
目前还有些兼容性问题，如噪音、手机莫名重启、FC、闪退等。如果您不能忍受，请不要安装。

【卸载说明】
1、卸载时只需进入V4A音效调节的设置内，选择“卸载/还原”，卸载驱动程序之后
2、再从谷歌市场卸载该应用即可
【驱动更新】
由于目前ViPER4Android的驱动是由该音效调试界面内，手动安装或卸载的，因此当您更新了ViPER4Android.apk之后还需要更新相应版本的音效驱动，才可以保证V4A正常的工作。（在驱动设置内，手动卸载并安装驱动，重启即可）

【CPU平台识别】
新版本的驱动已经更换了CPU平台的命名，对应关系如下：
中兴u880或与之使用相同CPU(PXA920)的机器，选择“没有VFP(PXA920)”
Tegra2、所有主频小于等于800MHz的CPU，选择“带有VFP的ARM”
主频大于800MHz的高通所有CPU、所有单核，选择“带有NEON的A8”
其他的所有双核、四核、八核，选择“带有NEON的A9/15”。
PS：由于高通使用了自己的架构，因此选择A8会比A9省电一些。

【假如你遇到了下列问题请参考】【没有遇到则无视】
1、针对Poweramp的用户：
打开Poweramp的设置->音频引擎->高级微调->直接音量控制关闭。
2、针对系统自带播放器(包括MIUI音乐播放器、Apollo等)：
在系统自带播放器中，若开启播放器的均衡器则会自动禁用V4A的音效，关闭播放器均衡器时才会自动启用V4A。
其他播放器待补充。。。。
XHIFI：耳塞的话建议细节使用0~30之间的值，过大的话会使高频太刺耳，低音轮廓可以大一些。

【脉冲反馈样本说明】
由于时常更新脉冲反馈样本，因此将不再随压缩包附带。
需要的网友可以访问http://forum.vipersaudio.com/forum.php?mod=forumdisplay&fid=49，这里是样本的集合区。

-----------如何使用好该音效设置？-------------
【FX版主要针对音频效果的渲染，通过调节各个参数以达到音频效果调整的目的。】

1、效果总开关。该选项定义了是否启用V4A的耳机音效，是总开关。
2、回放增益控制
回放增益控制主要用于动态控制音频的音量，放大或衰减。
(1)、启用。是否启用该效果。
(2)、效果强度。效果强度代表音量放大或衰减的速度，越强则速度越快，最终音量也越大，越弱则速度越慢，最终音量越接近音频原始音量。推荐中等。
(3)、最大增益倍数。当音频的音量过小时，回放增益为了将音量放大到设定的水准，可能会有非常大的放大倍数。该值越大则音量越大，太大时也会将歌曲内的噪音放大。推荐4倍。
(4)、最大音量。该值定义了从回放增益出来的声音的最大音量分贝值，值越大音量越大，0分贝代表数字信号的最大值。为了使声音更柔和，推荐-1.9分贝。

【XHiFi版设置】
1、效果总开关。该选项定义了是否启用V4A的耳机/蓝牙音效，是总开关。
2、回放增益控制。同FX版中耳机的回放增益。
3、FIR均衡器
XHiFi的FIR均衡器采用10段2047阶线性FIR均衡器，质量远高于FX版的均衡器。
调节方法同FX版中耳机的FIR均衡器。
4、音频重整
音频重整是XHiFi版的核心内容，主要用于对MP3等有损音乐进行细节和高音补偿。目前处在参数调整阶段，不同的设备可能会有不同的听感。
(1)、启动。是否启用该效果。
(2)、细节解析度。该值定义了还原多少百分比的细节和高音，值越大则声音的细节越多，高音也越强。
对于一般耳塞，现阶段不建议开启该功能，可能会出现高频刺耳。
对于魔音/飞利浦/僵尸/森海/白牙/AKG等好一些的耳塞，该值建议30~50。
对于高档头戴式耳机，需要根据耳机线长来设置该值，基数为40，线每长80公分值增加10。
对于手机后接驳前级放大器/耳放等，基数为60，耳机线每长80公分值增加10。
若接驳电子管放大器，则直接使用100。
(3)、低音轮廓。该值定义了重建低音的轮廓占到总频带的百分比，该值越大则低音越强，但中音和细节会稍微丢失。
对于耳塞建议使用50~70，头戴式耳机使用20~30。
5、总输出门
这个选项就是V4A的输出限幅器，用于防止音量过大造成削波失真。
(1)、限制级别。该值定义了限幅器限制的波形幅度最大级别，0分贝是数字信号的最大值。该值越小则越容易出现音频被压缩的听感(音量也越小)，会损失声音细节，但可以有效控制最终输出的音量。建议0分贝。

[v2.1.0.1]
1、新增一个差分环绕效果。
2、增加声道平衡设定。
3、细化场环绕的设置。

(In the driver settings, manually uninstall and install the driver, you can restart)

[CPU platform recognition]
    The new version of the driver has been named to replace the CPU platform, the corresponding relationship is as follows:
    ZTE u880 or in connection with the same CPU (PXA920) machine, select "No VFP (PXA920)"
    Tegra2, all speeds less than or equal to 800MHz CPU, select the "ARM with the VFP"
    Speeds greater than 800MHz Qualcomm all CPU, all single-core, select "with NEON's A8"
    All other dual-core, quad-core, eight-core, select "with NEON's A9 / 15".
    PS: Because Qualcomm uses its own infrastructure, so choose A8 A9 power than some.

[If you encounter problems, please refer to the following] [ignore] is not met
1, for the Poweramp users:
Open Poweramp the Settings -> Audio Engine -> Advanced tuning -> Direct volume control is turned off.

Other players to be added. . . .
XHIFI: earplugs if the proposed details of the use value between 0 to 30, too large, then make high frequency is too harsh, bass contour can be larger.

[Description] sample pulse feedback
Because frequently updated sample pulse feedback, and therefore will not pack that came with the compression.
Users need to access http://forum.vipersaudio.com/forum.php?mod=forumdisplay&fid=49, here is a sample collection area.

----------- How good the sound settings? -------------
[FX version mainly for rendering audio effects by adjusting various parameters in order to achieve the purpose of adjustment of audio effects. ]

1, the total effect of the switch. This option defines whether V4A enabled headphone sound, is the master switch.
2. Replay Gain Control
    Playback gain control is mainly used for dynamic control audio volume, amplification or attenuation.
    (1) enabled. Whether the effect is enabled.
    (2), the effect of strength. The effect of strength on behalf of amplification or attenuation rate of the volume, the stronger it is, the faster, the final volume is larger, the weak, the slower the speed, the final volume of the audio closer to the original volume. Recommended medium.
    (3), the maximum gain multiplier. When the audio volume is too small, Replay Gain to amplify the volume to the set level, there may be a very large magnification. The higher the value the louder the volume is too large will also amplify the noise within the songs. Recommended 4 times.
    (4), the maximum volume. This value defines the maximum value from the playback volume decibel gain out of the sound, the higher the value the greater the volume, maximum 0 db on behalf of the digital signal. In order to make the sound softer, recommend -1.9 dB.

XHiFi [Settings]
1, the total effect of the switch. This option defines whether V4A enabled headset / Bluetooth audio, is the master switch.
2, the playback gain control. FX version with headphone playback gain.
3, FIR equalizer
    XHiFi the FIR equalizer section 2047 in a 10-order linear FIR equalizer, the quality is much higher than the FX version of the equalizer.
    Adjustment method with FX Edition headphones FIR equalizer.
4, audio restructuring
    Audio reforming is XHiFi version of the core content, mainly used for MP3 and other lossy music details and treble compensation. Currently in the parameter adjustment phase, different devices may have a different sense of hearing.
    (1), starts. Whether the effect is enabled.
    (2), details of the resolution. This value defines the percentage reduction of detail and treble, the more value the greater the sound of the details, the stronger the treble.
        For general ear, turn on this feature is not recommended at this stage, there may be a high-frequency harsh.
        For the magic sound / Philips / zombie / Sennheiser / White Teeth / AKG, etc. better ear, the value of 30 to 50 is recommended.
        For high-end headphones, the headphone cable needs to be set according to the length of the value, the base is 40, line 80 km long each score increased by 10.
        After connecting the phone to the preamp / amp, etc., base 60, the headphone cable length per 80 male scores increased by 10.
        If the feeder tube amplifier, the direct use of 100.
    (3), the bass contour. This value defines the percentage of the total accounted for contour reconstruction bass band, the larger the value, the stronger the bass, midrange detail but slightly lost.
        Earplugs are recommended for 50 to 70, 20 to 30 using a headset.
5, the total output of the gate
    This option is V4A output limiter to prevent excessive noise caused by clipping.
    (1), limit level. This value defines the maximum level waveform amplitude limiter limits, 0 db is the maximum value of the digital signal. The smaller the value, the more prone to listen to audio is compressed sense (the volume is smaller), the sound will lose detail, but can effectively control the final output volume. Recommendation 0 db.
