原文：Audio Device Document 1.0(PDF) USB Device Class Definition for Audio Devices Release 1.0 March 18, 1998 86 5.2.2.5.1 Set Processing Unit Control Request This request is used to set an attribute of an audio Control inside a Processing Unit of the audio function. Table 5-36 Set Processing Unit Control Request Values bmRequest Type bRequest wValue wIndex wLength Data 00100001B SET_CUR SET_MIN SET_MAX SET_RES CS Processing Unit ID and Interface Length of parameter block Parameter block The bRequest field indicates which attribute the request is manipulating. The MIN, MAX, and RES attributes are usually not supported for the Set request. The wValue field specifies the Control Selector (CS) in the high byte and zero in the low byte. The Control Selector indicates which type of Control this request is manipulating (Enable Processing, Mode Select, etc.) If the request specifies an unknown or unsupported CS to that Processing Unit, the control pipe must indicate a stall. For a description of the parameter block for the Processing Unit Controls, see Section 5.2.2.5.3, “Processing Unit Controls.” 5.2.2.5.2 Get Processing Unit Control Request This request returns the attribute setting of a specific audio Control inside a Processing Unit of the audio function. Table 5-37 Get Processing Unit Control Request Values bmRequest Type bRequest wValue wIndex wLength Data 10100001B GET_CUR GET_MIN GET_MAX GET_RES CS Unit ID and Interface Length of parameter block Parameter block The bRequest field indicates which attribute the request is reading. The wValue field specifies the Control Selector (CS) in the high byte and zero in the low byte. The Control Selector indicates which type of Control this request is addressing. (Enable Processing, Mode Select, etc.) If the request specifies an unknown or unsupported CS to that Unit, the control pipe must indicate a stall. For a description of the parameter block for the Processing Unit Controls, see Section 5.2.2.5.3, “Processing Unit Controls.” 5.2.2.5.3 Processing Unit Controls Processing Unit Controls are in principle specific to the type of process a Processing Unit implements. However, instead of specifying all supported Controls on a per process basis, it was considered more efficient to create a ‘pool’ of possible Controls. In this way, Controls that occur in different Processing Units need only be specified once. However, the Control Selector Codes and the bit positions in the bmControls field of the Processing Unit descriptor are assigned on a per-process type basis. Issuing nonsupported Control Selectors to a Processing Unit leads to a control pipe stall. USB Device Class Definition for Audio Devices Release 1.0 March 18, 1998 87 The following paragraphs present a detailed description of all possible Controls a Processing Unit can incorporate. For each Control, the layout of the parameter block together with the appropriate Control Selector is listed for all forms of the Get/Set Processing Unit Control request. The Control Selector codes are defined in Section A.10.3, “Processing Unit Control Selectors.” 5.2.2.5.3.1 Enable Processing Control The Enable Processing Control is used to either enable the functionality of the Processing Unit or bypass the Processing Unit entirely. In the latter case, default behavior is assumed. Enable Processing Control can have only the current setting attribute (CUR). The position of an Enable Processing switch can be either TRUE or FALSE. The current setting of the Control can be queried using a Get Processing Unit Control request. Table 5-38 Enable Processing Control Parameter Block Control Selector XX_ENABLE_CONTROL wLength 1 Offset Field Size Value Description 0 bEnable 1 Bool The setting for the Enable Processing Control CUR attribute. Enabled when TRUE, disabled when FALSE. 5.2.2.5.3.2 Mode Select Control The Mode Select Control is used to change the behavior of the Processing Unit. A Mode Select Control can support all possible Control attributes (CUR, MIN, MAX, and RES).The valid range for the CUR, MIN, and MAX attributes is from one to the number of modes, supported by the Processing Unit (reported through the bNrModes field of the Processing Unit descriptor). The RES attribute can only have a value of one. The Mode Select Control honors the request to the best of its abilities. It may round the bMode attribute value to its closest available setting. It will report this rounded setting when queried during a Get Processing Unit Control request. Table 5-39 Mode Select Control Parameter Block Control Selector XX_MODE_SELECT_CONTROL wLength 1 Offset Field Size Value Description 0 bMode 1 Number The setting for the attribute of the Mode Select Control. 5.2.2.5.3.3 Spaciousness Control The Spaciousness Control is used to change the spatial appearance of the stereo image, produced by the 3D-Stereo Extender Processing Unit. The Spaciousness Control can support all possible Control attributes (CUR, MIN, MAX, and RES). The valid range for the CUR, MIN, MAX, and RES attributes is from zero to 255%. The Spaciousness Control honors the request to the best of its abilities. It may round the bSpaciousness attribute value to its closest available setting. It will report this rounded setting when queried during a Get Processing Unit Control request.

Audiosurf Audiosurf関連サイト Audiosurf Steam配信の音楽パズルゲーム。9ドル程度と非常にお安いのですが、デモ版でプレイです。 （スクショはhttp //www.4gamer.net/より） PCに入っている音楽ファイルをしているすると、Audiosurfがそれを解析してステージやブロックの配置パターン、移動速度を決める、という感じのゲームです。Playstationのビブリボンを思い出したりするのですが、音楽ファイルの数だけステージが楽しめますよ、てなわけで、そんなに楽しむかどうか措いておくとして、ブロックを取ったり消したりの交換音が微妙に音楽にマッチして気持ちよかったりする、というの世間の評判のようです。 ということでプレイの様子です。 落語やお経でも試してみたのですが、まあステージはもちろん構成されますが、それを聞きならがプレイして楽しいのかというと、人それぞれですが。 関連サイト 公式サイト http //www.audio-surf.com/ 4Gmaers http //www.4gamer.net/games/046/G004693/
