- IBM Thinkpad Mwave DSP Patch for WAV files on Windows 95
- ========================================================
-
- This patch is intended to fix the following problem:
-
- Mwave may malfunction when playing WAV files recorded with
- sampling rates of exactly 11,000 Hz, 22,000 Hz, and 44,000 Hz.
- Symptoms include:
-
- - Mwave stops functioning after attempting to play a WAV
- file recorded at a sampling rate of exactly 11,000 Hz.
- Windows 95 is still operational, but no Mwave function is
- available. Windows 95 must be restarted to restore Mwave
- function.
-
- - Mwave plays slowly WAV files recorded at a sampling rate
- of exactly 22,000 Hz.
-
- Wave files recorded at the more common sampling rates of
- 11,025 Hz, 22,050 Hz, and 44,100 Hz are not affected.
-
- NOTE: To check the sampling rate of a WAV file in Windows 95,
- do the following:
- - View the file using Windows Explorer.
- - Right Click on the WAV file name.
- - Click on the Details tab. The Audio Format line
- indicates the sampling rate used to create the file.
-
-
-
- This patch is intended for limited distribution to IBM customers. It has
- received only limited testing before release by IBM, therefore it is
- suggested that any critical data on your hard drive be backed up before
- applying it. This patch will become obsolete with the next release of
- Mwave code.
-
-
- Patch Scope
- ===========
- This patch is intended for Mwave version 2.1 *ONLY* running under
- Windows 95. To confirm your Mwave version:
-
- - From Windows 95, click on Start, then Run
- - Type C:\MWW\MANAGER\MWLEVELS.EXE and press Enter
- This will display information from the MWAVE.INI file.
- The Mwave version information is on the line starting with
- "OEM=". Mwave 2.1 reads:
- "OEM=Mwave ThinkPad Release 2.1"
-
- NOTE: If the patch is already installed, the following line will
- also be displayed:
- "Patch1=Wave Fix for 11000 Hz Wave Play"

- Patch Prerequisites
- ===================
- Mwave version 2.1 must be loaded on your computer running under
- Windows 95.
-
-
- Patch Instructions
- ==================
- 1. Remove this diskette from the diskette drive.
-
- 2. Shutdown Windows 95 and restart the computer in MS-DOS mode.
- (Click on Start, then Shutdown, then Restart the computer in MS-DOS
- Mode).
-
- 3. At the C:\ prompt, type "a:\install" .
-
- 4. Install will try to locate all of Mwave. If everthing is not
- found (probably because you used directory names other than
- the Mwave default ones, or because Mwave exists on another
- drive) it does not matter. The ONLY directory that has to be
- located is the Mwave Windows Directory (MWW). If the
- directory found is incorrect, then reply "no" when install
- asks if everthing is correct. Install will then prompt you
- to type in the correct pathname.
-
- 5. Type "exit" to restart Windows 95
