volume

We have observed that using javascript-based audio from a browser, the output level is not correctly linearly proportional to the input signal level on many systems. For example, if you 'play' two sin waves with amplitude varying by 20dB, the resultant difference from different devices/settings may be markedly different from 20dB, e.g. as far off as 10dB or less. We need to put out simple audio signals (e.g. sin waves) at calibrated decibel levels relative to each other, for example put out one sin wave at one volume, then put out another sin wave that is 20dB quieter than the first one, and

5.1和6.0以上获取SD卡和USB(OTG)存储大小： 要获取存储设备的存储大小，先需要获取设备的路径，我这里的设备SD卡都只有一张，固定为/mnt/external_sd，USB口可能有多个，网上说的一般是/mnt/usb_storage，但我找个几个5.1的平板都获取不到，最后通过adb shell df查看到了usb的实际路径并打印出所有路径，重新写了份获取USB路径的流程，整理如下： https://blog.csdn.net/l471979773/article/details/84890492 public class StorageUtil { Context context; private String usb_dir = null; private String sdcard_dir = null; private List<String> sdcard_list = null; private List<String> usb_list = null; String TAG ="StorageUtil" ; public StorageUtil(Context context) { this.context = context; sdcard_list = new ArrayList<String>(); usb_list = new ArrayList

I have a closed surface mesh generated using Meshlab from point clouds. I need to get a volume mesh for that so that it is not a hollow object. I can't figure it out. I need to get an *.stl file for printing. Can anyone help me to get a volume mesh? (I would prefer an easy solution rather than a complex algorithm). Given an oriented watertight surface mesh, an oracle function can be derived that determines whether a query line segment intersects the surface (and where): shoot a ray from one end-point and use the even-odd rule (after having spatially indexed the faces of the mesh). Volumetric

On my Kubernetes cluster on GKE, I have the following persistent volume claims (PVCs): kind: PersistentVolumeClaim apiVersion: v1 metadata: name: registry spec: accessModes: - ReadWriteOnce resources: requests: storage: 100Gi and: kind: PersistentVolumeClaim apiVersion: v1 metadata: name: postgresql-blobs spec: accessModes: - ReadWriteOnce resources: requests: storage: 100Gi Amongst others, I have the following persistent volume defined: kind: PersistentVolume apiVersion: v1 metadata: name: pv0003 spec: capacity: storage: 100Gi accessModes: - ReadWriteOnce - ReadOnlyMany gcePersistentDisk:

获取手机里所有存储设备盘符,首先需要得到挂载在手机上的有哪些盘符,这里需要用到一个被系统隐藏的方法， 即StorageManager下的getVolumePaths()方法。具体通过反射得到。 方法返回值为字符串数组， getVolumeList返回所有相关信息 StorageVolume: mStorageId=131073 mPath=/storage/external //盘符（路径） mDescriptionId=17040902 mPrimary=false mRemovable=true //是否可卸载，内置SD卡无法卸载，外置SD卡可以卸载，据此可判断是否存在外置SD卡， //这样在某些APP中可以将某些数据优先存储到外置SD卡，优化存储空间资源的分配。如相机 mEmulated=false //是否是内置SD卡 mMtpReserveSpace=0 mAllowMassStorage=true mMaxFileSize=0 mOwner=null mUuid=4041-5DA0 mUserLabel=null mState=mounted //是否已载入（可用） public class StorageUtils { /* 获取全部存储设备信息封装对象 */ public static ArrayList<Volume> getVolume (Context

I want to use AVAudioPlayer and cross fade more than 2 mp3 files. I have 5 mp3 files and 5 pages "myScrollView" with UIScrollView class and pagingEnabled = YES. When user move page, I want to play each songs for each page with volume fade out for previous mp3 file and fade in for next mp3. Please help this problem. This is not cross fading operation. But, this can fade-in/out one at a time with new thread using NSOperation and fade-in/out effects can be added to the thread in any order. I found Linear fade Object MXAudioPlayerFadeOperation created by Andrew Mackenzie-Ross on 30/11/10. mackross

由于不同芯片设备的外部存储设备不太统一，比如说外部sdcard,u盘等，他们的路径在不同芯片上面的定义是不一样的，所以我们需要动态的去获取机器当前的外部设备mount 的情况 Android 通过 StorageManager 类来管理存储设备的，这个类里面包含一些隐藏的方法： getVolumeList —–> 返回StorageVolume 类型的数组，包含系统所有的存储设备volume getVolumePaths—–> 返回String 类型的数组,包含系统所有存储设备的挂在路径 以下以getVolumeList 为例来获取系统所有的可插拔的设备 priavte StorageManager mStorageManager; private Method getStorageVolumes ; private Method getPath ; mStorageManager = (StorageManager) getSystemService(Context.STORAGE_SERVICE); try { getStorageVolumes = mStorageManager.getClass().getMethod("getVolumeList"); StorageVolume[] volumeList = (StorageVolume[])

I have a path to a partition. How can I retrieve UUID of that partition programatically without using terminal commands? An example will be more helpful. You can use the Disk Arbitration framework ( Apple reference ). There is also a good summary at this blog by Chris Suter. You can get the UUID by using the kDADiskDescriptionMediaUUIDKey. Aaron Burghardt described it well in this mailing list thread . Here is a quote from that link: Once you have the DADisk, use DADiskCopyDescription to get a dictionary of properties, in which you will find the UUID with the key kDADiskDescriptionMediaUUIDKey
