TRUESPEECHWAVEFORMAT
構造体サイズ=各フィールドのバイト数(x64/x86 で異なる場合は x64/x86 と併記)。x64/x86 列=フィールドのバイトオフセット(HSPで dupptr / lpoke / wpoke 等に使用)。
フィールド
| フィールド | 型 | サイズ | x64 | x86 | 説明 |
|---|---|---|---|---|---|
| wfx | WAVEFORMATEX | 18 | +0 | +0 | 波形フォーマットの基底となるWAVEFORMATEX構造体。DSP Group TrueSpeech形式を示す。 |
| wRevision | WORD | 2 | +18 | +18 | コーデックのリビジョン番号。フォーマットのバージョンを示す。 |
| nSamplesPerBlock | WORD | 2 | +20 | +20 | 1ブロックあたりのサンプル数。デコード単位を示す。 |
| abReserved | BYTE | 28 | +22 | +22 | 予約済みバイト配列。将来の拡張用で通常はゼロ。 |

}HSP用 定義
HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。
; HSP3.7/3.8 は構造体機能が無いため、4byte整数の配列変数で操作します。(x64 レイアウト)
; TRUESPEECHWAVEFORMAT サイズ: 50 バイト(x64)
dim st, 13 ; 4byte整数×13(構造体サイズ 50 / 4 切り上げ)
; wfx : WAVEFORMATEX (+0, 18byte) varptr(st)+0 を基点に操作(18byte:入れ子/配列)
; wRevision : WORD (+18, 2byte) wpoke st,18,値 / 値 = wpeek(st,18)
; nSamplesPerBlock : WORD (+20, 2byte) wpoke st,20,値 / 値 = wpeek(st,20)
; abReserved : BYTE (+22, 28byte) varptr(st)+22 を基点に操作(28byte:入れ子/配列)
; ※4byte境界の整数は添字 st.N(N=オフセット/4)で読み書き可。それ以外は peek/poke 系を使用。; IronHSP は NSTRUCT(構造体)をサポート。32bit/64bit どちらでも同じコードで動作します。
